Look at the Python 3 urllib module, which provides various functions to allow you to read stuff via URLs.

Chris' suggestion will work, but have you considered using wget or curl? They do what you want, are well documented and tested. No need to reinvent the wheel.

prasad ap,
Your post was moved to a new topic. See below.

Now we're talking about converting between file formats, I don't think this is really a Python question any more, so I thought you might get more help in a more general forum (General Computing).
