Python 9. Basics First we will have a look at urrllib2 library in python.
The response header is somewhat different for files than webpages, it looks like Content-Disposition: It is as simple as doing if 'Content-Disposition' in str header: It is a file Now to download and save it, we can proceed the same way as last one with open "myfile", "wb" as code: Share this: Like this: Like Loading OR filters with Django-filter May 20, Add caching to speed up your site: Make a certificate creator using Python June 16, May 6, at Kunal Grover says: May 7, at Raptors95 says: May 16, at 1: May 16, at AE says: December 6, at 9: March 30, at 8: Python Examples says: March 10, at 4: Execute the above script and go to your "Downloads" directory.
You should see the downloaded pdf document as "cat2. You can also download files using requests module. The get method of the requests module is used to download the file contents in binary format.
You can then use the open method to open a file on your system, just like we did with the previous method, urllib2. In the above script, the open method is used once again to write binary data to local file.
If you execute the above script and go to your "Downloads" directory, you should see your newly downloaded JPG file named "cat3. With the requests module, you can also easily retrieve relevant meta-data about your request, including the status code, headers and much more.
In the above script, you can see how we access some of this meta-data. If you need to add customer headers, for example, all you need to do is create a dict with your headers and pass it to your get request:.
There are a ton more options and features to this library, so check out their great user guide for more info on how to use it. One of the simplest way to download files in Python is via wget module, which doesn't require you to open the destination file.
The download method of the wget module downloads files in just one line. The method accepts two parameters: Here you should see your newly downloaded "cat4.
In this article we presented four of the most commonly used methods to download files in Python. Personally, I prefer to use the request module for downloading files due to its combination of simplicity and power.
However, your project may have constraints preventing you from using 3rd party libraries, in which case I'd use the urllib2 module for Python 2 or the urllib.

We used the bar method of progress module while writing the content into the file. The output will look like the following: Download a Webpage Using urllib In this section, we will be downloading a webpage using the urllib.
The urllib library is a standard library of Python, so you do not need to install it. The following line of code can easily download a webpage: urllib. The file extension will be.
Check the following code: import urllib. Then, we made the request to retrieve the page. Then, you can retrieve the file. Using urllib3 The urllib3 is an improved version of the urllib module.
You can download and install it using pip: pip install urllib3 We will fetch a web page and store it in a text file by using urllib3. Import the following modules: The shutil module is used when working with files. Then, we have the unzip parameter.
If it is True, the downloaded file will be unzipped in the same destination folder. In this example, we download the zip folder, and then, the folder is unzipped.
