How can I modify python warnings?

Question

I have a requirement where I need to modify a python warning i.e I need to print a "user-friendly" warning message If I get a warning from the code. I don't want the file name on stdout.

with requests.get(url, stream=True, timeout=300,verify='/etc/ssl/certs/') as r:

I get a warning which prints the file name if the URL is self-signed.

@MauriceMeyer No, It's not duplicate. There is a difference between "suppress" and "modify" — Ashwani, Oct 05 '19 at 17:22
@shaikmoeed Thanks, I got the solution, we can get the warning in a warning object and we can do whatever with that after. — Ashwani, Oct 05 '19 at 17:24
@Ashwani you may want to add an answer illustrating the solution... — Dan Cornilescu, Oct 05 '19 at 18:38

 with warnings.catch_warnings(record=True) as w:
    with requests.get(url, stream=True, timeout=300, verify='/etc/ssl/certs/') as r:
       if w: 
          print w[0].message

If there is any warning returned by request.get() then that warning will be available in w[0].message variable and If you want to modify it, you can.
