Python warning print expression is assigned to nothing

Question

I'm using Syntastic in vim as a linter for Python3. I have a few warnings that my print statements are expressions that are not assigned to anything:

[expression-not-assigned] Expression "(print(('Authenticated for Twitter user ') + (twitter_api.VerifyCredentials().screen_name)), )" is assigned to nothing
[expression-not-assigned] Expression "(print('Deleting Twitter posts.'),     )" is assigned to nothing

These are just simple print statements so I'm curious why I'm seeing these warnings and how I would go about resolving them.

@yurikilochek Yes, in order to get things to print on new lines. Is there a better way to do that? — Alex Waibel, Aug 13 '17 at 18:27
Well, turns out the commas were completely unnecessary... I feel dumb. — Alex Waibel, Aug 13 '17 at 18:32

Remove the outer parenthesizes and everything should be fine.

print('Authenticated for Twitter user %s' % twitter_api.VerifyCredentials().screen_name)
print('Deleting Twitter posts.')

That actually is how those statements appear in my code already. – Alex Waibel Aug 13 '17 at 18:16
