However you choose to work on the file, knowing the basic building blocks is essential in creating a finished product that presents your book to its best advantage. All of the content between those tags is said to be part of that container. Now, to make things just a bit more complicated, tags can also take what are called attributes, which tell the ereader how to treat certain tags. An attribute is always added by including the attribute name, an equal sign, straight quotes, and a value. What a surprise! I could also have had the attribute read left, justify, or center. Many of them can be nested — that is, placed inside another block tag. Note that when you nest tags, you must always close the most recently opened tag first. The advantage to this is that you can place the tags on separate lines of code from the text, which makes it easier to see what tags are still open. Nor will the white space between the paragraphs. The only things that will create a space between paragraphs in a web page or an ebook is a block tag. Usually this text is displayed in a smaller font size and indented further — but this can be controlled through CSS.

The source src attribute tells the ebook reader where to look for the image file. If you would like to learn more about them, check out the IDPF accessibility guidelines , which offer a wonderful overview of the ePub3 format. If you copy that into a text editor and save it with the file type html, you can open it with your web browser.

Go you! It can be used for identification purposes, or, most commonly, for formatting the text. Identity code: the ID attribute By the way, by adding an id attribute, you can turn any of these tags into anchors — locations within the file. A great free resource is the online reference W3Schools.

There are tutorials, examples, and all sorts of great information. Time to bring on the style!

Are you prepared to work fixed hours? Will your family support a new career choice? Do you enjoy watching and participating in construction work? Do you stop on the way to work to watch a house being built? Do you enjoy looking at construction plans? If you're not involved in construction, have you participated in any construction projects? Do you enjoy working with construction tools and equipment? Did you do well in shop classes in school? Can you anticipate at least some problems in a construction project before work begins?

Are you highly organized and efficient in your daily life? Are you detail oriented comfortable following rules and procedures exactly?

Do you have a good memory? Are you comfortable discussing an issue with others before reaching a decision? Can you function effectively under stress? Are you persuasive? Can you convince others to follow Your suggestions? How do you deal with your own mistakes? With mistakes made by others? Do you fix the problem, or affix the blame? How do you react to confrontations? Are you confident about your success in this career? Are you safety conscious? Do you understand that a career in code compliance and enforcement requires a major personal commitment?

Do you know any building inspectors? Does their lifestyle appeal to you? Now, let's look at the role you'll play if you get the job. You'll wear many hats as a code enforcement professional. Ideally, you'll be assigned responsibilities that match your background and level of knowledge. Most building inspectors wear two hats, one as the code police and a second as a teacher or student.

As a building safety expert, your decisions will normally be final. When wearing the enforcement hat, be careful about giving an opinion without careful thought.

Avoid making commitments beyond your scope of authority. And since no building inspector knows everything about construction, you'll also be a student from time to time. Know the Code You'll never stop learning about the code because it's constantly changing. Every time someone dies or is injured in a building failure, whether from fire, wind or earthquake, there's a lesson to be learned. If a death or injury was avoidable, as a Building Official, you have the authority to propose changes to the code.

Most of what you read in the ICC can be understood as an attempt to prevent repetition of mistakes made in an earlier time by others. I recommend that you learn both what the code says and why it's that way. This book is loaded with the "why" of what's in the code the history of code development. I think this is interesting. Even if you don't agree, knowing the "why" will help you respond to questions from builders.

If you don't know the reason for some provision in the code requirement, your only answer to an objection will be, "Because it says so.

If you're more interested in compliance than debating points, understand the reason for the rule as well as you understand the rule. Most builders, once they understand the reason, will find a way to comply, with little or no objection.

Most of Chapter 2 of this book is devoted to the history of code development. I consider this information an essential part of your preparation for both the interview and the job. Ever, code expert needs to know how the code came to be the whys and wherefores.

You'll encounter conflicts between different codes and even within the same code. Generally these inconsistencies will be a matter of interpretation. But when the contractor shows you a code section that seems to support his claim, and you've just shown him one that supports your position, you have a problem. In most all these cases, it comes down to intent.

What was the goal of the code writers on this issue? You need to know. If the goal is still achieved by the contractor's interpretation, I recommend going along.

You'll also need to know about the more obscure parts of the code, like Special Inspection and Structural Observation. For example, some buildings will be subject to demolition if dangerous conditions are present. How do you know what to look for? What happens when the building code seems to conflict with industry standards? Which prevails?

Record Keeping Another role for the building inspector: very careful record keeping. You'll be making decisions that affect public safety, including some life-or-death matters. Nearly every decision will affect a contractor's profit or loss on the job. Ever, dispute is a potential lawsuit. You need a written record of what you observed and what you decided. You're not going to remember what happened on a job several years ago. But if you're called into court, every judge will permit a witness to "refresh" his or her recollection by referring to notes made just after the event occurred.

You don't want to be on the witness stand trying to remember what you found on a jobsite one morning two years ago and what you told the contractor. You visit dozens of jobs every week. Your memory isn't that good. And these records must be legible clear enough to be read and understood by someone else should that need arise. A judge isn't going to be impressed with your halting guesses at what you might have meant by the scribbles you put in a ledger some time back — and neither will your supervisor.

People Skills Your inspection standards should, as nearly as possible, match the inspection standards of every other inspector in your office. The results of any inspection shouldn't depend on who was assigned to the job. Uniform code enforcement is important. Since you'll most likely be just one of a team of inspectors, it's important that you and the other inspectors apply the same standards and issue the same messages to contractors.

You'll have many opportunities to coordinate and harmonize standards with other inspectors. Just as every thumbprint is different, every inspector is different. Each of us probably has our own special "thing" that bugs us when it's done wrong. We look for it and we clamp down when we see it. Maybe you get especially upset when carpenters forget the expansion joints in roof sheathing you keep telling them and they keep forgetting it and it so bugs you.

The next inspector actually counts nails and will fail a job if a sheet is a nail short. Pretty soon, the building community gets to know which inspector watches for expansion joints and which inspector will let expansion joints slide. Builders find a way to get the inspector they prefer. That's poor policy in any building department. All builders in your community should understand that inspectors in your office follow uniform standards. In the same vein, it's not fair to the builder if one inspector fails the job for lack of expansion joints and the second inspection is done by Mr.

Nail Counter. Learn the fine art of maintaining professional and yet personal relationships within the construction community.

This requires walking a fine line. No matter how carefully you walk that line, there will be complaints about your inspections. You're in the code enforcement business. Those getting enforced can't be expected to like it. But avoid making adversaries out of the contractors you deal with. Keep in mind the expression, "Pick your battles.

Some confrontations simply aren't worth the effort and the bad feelings. Avoid nitpicking every little defect. Save your ammunition until something truly important needs to be fixed. Occasionally you'll be asked to resolve a dispute between an owner and a builder.

While this is a compliment — they believe in your expertise and trust your judgment and impartiality — it can also be a minefield.

You don't know what was in the contract, you don't know what has already taken place, and you don't know contract law. In these cases, just state what you do know, which is what the code requires. If you know the code section, cite it by section number. If you have an opinion that goes beyond what's in the code or the reason for the rule, I recommend keeping that opinion to yourself. Resist the temptation to play Hammurabi. Communication Skills Suppose you're talking to a builder over the phone about a project.

Try to visualize the work. Seeing it in person is, of course, far better. But most inspectors don't have the luxury of buzzing across town to have a look in person. Sometimes the phone is your only option. Good communication skills come with practice and experience. But half of good communication involves listening carefully and asking the right questions. The contractor has a mental picture of what he or she is describing. You'll have a second picture.

Ideally, those two mental pictures will coincide. Occasionally you'll have a code question that can't be resolved — even after your explanation of the rule and the reason for the rule. If the builder still insists that you're off base, it's probably time to call in your supervisor, referred to as the "building official" in the code.

I'll talk more about that in later chapters. So, if you think you can handle all these things, and would enjoy being a code enforcement official, read on. If you've decided this is what you want to do, let's deal with getting you the job. Getting the Job Building inspectors, plans examiners, permit technicians and building officials are hired by public agencies such as a city, county, parish, state, or commonwealth. You get the job by demonstrating qualifications superior to other candidates.

Hiring is, for the most part, similar to hiring in the private sector. One significant difference is that there are more rules. Openings and Applications Most openings must be advertised for a certain amount of time. Applications are usually screened by a Human Resources Department HR in the agency and then forwarded to the hiring authority. To get past the initial screening, he sure your application is complete. If you meet the minimum qualifications for the position, you'll be certified and your name will be put on what's typically called the Cert List.

The HR department head will usually ask the building official to help pick candidates to interview from this list. Generally, the list will be short enough that all candidates get an interview. But in larger municipalities, and when the competition is greater, only the best-qualified candidates will be grunted an interview. The Interview When you're called for an interview, listen to the instructions carefully. To prepare, get a copy of the code being enforced.

Study any sections that aren't familiar to you. Take notes. Study guides offered by the ICC cover subjects likely to be discussed in a placement interview.

Many publications offer suggestions for job interviews. My suggestion is to simply be yourself. Don't try to over-impress. HR people read those books too. And they'll know when you're repeating something you've been coached to say.

If you're given any instructions to prepare for the interview, follow them closely. The interview panel that wrote instructions for the interview is sure to favor applicants who follow those instructions. Your preparation and cooperadon assure the panel that you understand the importance of following instructions.

If you have the opportunity, try to get an early appointment. Interviewers are fresher in the morning. By afternoon, the panel will be tired of asking the same questions and hearing many of the some answers. Expect the questions to be similar for most applicants.

This is a fair practice and gives each candidate the same opportunity to understand the nature of a question. Don't be surprised at how structured the interview is.

For example, if you don't understand a question, the interviewer may only be permitted to repeat the question once, with no further explanation.

If you don't get it, then that's part of the test. The interviewer wants to see if your understanding is on the same level as that of the other candidates. Study the glossary in the back of this book to brush up on construction terms.

Think carefully before you answer any question. Many questions will test your professional competence. For example, you'll probably be asked for a summary of your experience in construction. Have you supervised construction? Or did you just work as a carpenter? Don't give in to the temptation to embellish on your experience.

This Python 3 tutorial will guide you through converting data types including numbers, strings, tuples and lists, as well as provide examples to help familiarize yourself with different use cases.

This tutorial will cover some variable basics and how to best use them within the Python 3 programs you create. We'll go through naming rules and conventions, reassigning variables, multiple assignment, and making local and global variables. This tutorial will guide you through some of the common uses of string formatters in Python, which can help make your code and program more readable and user friendly.


This tutorial will go over operators that can be used with number data types in Python. This tutorial will go through a few of the built-in functions that can be used with numeric data types in Python 3. Becoming familiar with these methods can give you more flexibility when programming. The Boolean data type can be one of two values, either True or False. We use Booleans in programming to make comparisons and to control the flow of the program. Understanding Lists in Python 3. This tutorial will go through some of the ways we can work with lists in Python.

Lists are great to use when you want to work with many related values. They enable you to keep data together, condense your code, and perform the same methods and operations on multiple values at once. This tutorial will cover some basic processes, including indexing, slicing, modifying, and concatenating lists.

List comprehensions offer a succinct way to create lists based on existing lists. In this tutorial, we will cover the syntax of list comprehension, which will be an important tool in creating efficient code.

A tuple is a data structure that consists of an immutable ordered sequence of elements. Because tuples are immutable, their values cannot be modified. In this tutorial, we will cover some basic processes, including indexing, slicing and concatenating tuples, and the built-in functions that are available when working with these data structures. Dictionaries map keys to values, making key-value pairs that can then store data. In this tutorial, we will go over the dictionary data structure in Python.

This tutorial will walk you through installing modules, importing modules, and aliasing modules. Modules are Python. They can create function definitions and statements that you can reference in other Python.

In Python, modules are accessed by using the import statement, which tells the current program to bring in the definitions and statements of the other relevant file s for its own use. This tutorial will guide you through writing Python modules for you or others to use within your program files.

This tutorial will take you through writing conditional statements in the Python programming language.

The Code Book

A while loop implements the repeated execution of code based on a given Boolean condition. The code that is in a while block will execute as long as the while statement evaluates to True. In this tutorial, we will go over how while loops work and how to construct them. In computer programming, loops allow us to automate and repeat similar tasks multiple times. In this tutorial, we will go over the break, continue, and pass statements in Python, which will allow you to use for and while loops more effectively in your code.

A function is a block of instructions that, once defined, both performs an action once the function is called and makes that action available for later use.

Functions make code more modular, allowing you to use the same code over and over again. Both can be used improve readability and convenience, and are best for situations where the number of inputs within the argument list will remain relatively small.

Object-oriented programming allows for variables to be used at the class or instance level. This tutorial will demonstrate the use of both class and instance variables in object-oriented programming in Python.

This tutorial will go through some of the major aspects of inheritance in Python, including how parent classes and child classes work, how to override methods and attributes, how to use the super function, and how to make use of multiple inheritance.

Polymorphism allows for flexibility and loose coupling so that code can be extended and easily maintained over time. This tutorial will go through applying polymorphism to classes in Python. How To Use the Python Debugger. In software development, debugging is the process of looking for and resolving issues that prevent computer software from running correctly. The Python debugger pdb provides a debugging environment for Python programs.

In this tutorial, we will go over how to work with pdb to implement an interactive debugging environment that you can use with any of your programs written in Python. The Python code module is a useful and quick tool for debugging because it can be used to emulate the interactive interpreter. This tutorial will cover how to work with this module to examine your code. How To Use Logging in Python 3.
