The importance of file downloading can be highlighted by the fact that a huge number of successful applications allow users to download files.
These are just a few of the applications that come to mind, but I’m sure you can think of many more. In this article we will take a look at some of the most popular ways you can download files with Python. Specifically, the urlretrieve method of this module is what we’ll use for actually retrieving the file. To use this method, you need to pass two arguments to the urlretrieve method: The first argument is the URL of the resource that you want to retrieve, and the second argument is the local file path where you want to store the downloaded file. In the above code, we first import the urllib. Next we create a variable url that contains the path of the file to be downloaded. Run the above script and go to your “Downloads” directory.
You should see your downloaded file named “cat. Python 3, and it may be deprecated at some point in the future. Because of this, I wouldn’t recommend using it in favor of one of the methods below. We’ve included it here due to is popularity in Python 2. Using the urllib2 Module Another way to download files in Python is via the urllib2 module. The urlopen method of the urllib2 module returns an object that contains file data. Note that in Python 3, urllib2 was merged in to urllib as urllib.
Therefore, this script works only in Python 2. The open method accepts two parameters, the path to the local file and the mode in which data will be written. Here “wb” states that the open method should have permission to write binary data to the given file. Execute the above script and go to your “Downloads” directory.
You should see the downloaded pdf document as “cat2. Using the request Module 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.
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. The same goes for extra parameters that are required on the HTTP 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.
Using the wget Module 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: the URL path of the file to download and local path where the file is to be stored. Here you should see your newly downloaded “cat4. Conclusion 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.

So now depending on your needs and skills you can choose to use pytest-play as a library or as a framework. In this article I’m going to show how to implement a Plone CMS based login test using the python-free approach without having to write any line of Python code.
