Python if statement: False vs. 0.0

Question

Is it possible to:

for k,v in kwargs.items()
    if v == None or v == '' or v == 1.0 or v == False:
       del kwargs[k]

without deleting the key if v == 0.0? (False seems to equal 0.0), and without deleting the keys who equal True.

Answer 1

Or you can put it like this :

if v in (None, '', 1.0) or v is False:

Answer 2

You should use v is False instead of v == False. The same applies for your comparison to None. See PEP 8 - Style Guide for Python:

Comparisons to singletons like None should always be done with 'is' or 'is not', never the equality operators.
