Python equivalent of a given wget command

Question

I'm trying to create a Python function that does the same thing as this wget command:

wget -c --read-timeout=5 --tries=0 "$URL"

-c - Continue from where you left off if the download is interrupted.

--read-timeout=5 - If there is no new data coming in for over 5 seconds, give up and try again. Given -c this mean it will try again from where it left off.

--tries=0 - Retry forever.

Those three arguments used in tandem results in a download that cannot fail.

I want to duplicate those features in my Python script, but I don't know where to begin...

Answer 1

There is also a nice Python module named wget that is pretty easy to use. Found here.

This demonstrates the simplicity of the design:

>>> import wget
>>> url = 'http://www.futurecrew.com/skaven/song_files/mp3/razorback.mp3'
>>> filename = wget.download(url)
100% [................................................] 3841532 / 3841532>
>> filename
'razorback.mp3'

Enjoy.

However, if wget doesn't work (I've had trouble with certain PDF files), try this solution.

Edit: You can also use the out parameter to use a custom output directory instead of current working directory.

>>> output_directory = <directory_name>
>>> filename = wget.download(url, out=output_directory)
>>> filename
'razorback.mp3'
