The urlopen method of the urllib2 module returns an object that contains file data. To read the contents of Note that in Python 3, urllib2 was merged in to urllib as urllib.

It works around an event loop that waits for an event to occur and then reacts to that event.
The reaction can be calling another function. This process is called even handling. The asyncio module uses coroutines for event handling. To use the asyncio event handling and coroutine functionality, we will import the asyncio module:. The keyword async tells that this is a native asyncio coroutine.
Inside the body of the coroutine, we have the await keyword, which returns a certain value. The return keyword can also be used. In this code, we created an async coroutine function that downloads our files and returns a message.
The wait function of asyncio waits for the coroutines to complete.

Download Large File in Chunks Consider the code below: The Python shell will look like the following when the chunks are downloading: Not pretty?
Don't worry, we will show a progress bar for the downloading process later. Let's create a simple function that sends the response to a file in chunks: Let's do it for each URL separately in for loop and notice the timer: Now, replace the for loop with the following line of code: ThreadPool 9.
To install the client module, type the following command: 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.Another way to download files in Python is via the urllib2 module.
Simply import the requests module and create your proxy object. I'd also like to suggest you have a look at Python's argparse library.
