What's the advantage of a trailing underscore in Python naming?

Question

I am used to naming Python arguments in this way:

my_argument=\'foo\'

what\'s the advantage if I do this instead:

my_argum         


        

Answer 1

PEP8 does not recommend this naming convention, except for names that would otherwise conflict with keywords. my_argument obviously does not conflict, so there is no reason to use an underscore and PEP8 does not recommend that you do.
