What is the most pythonic way to check if a variable is not None? [closed]

python

The two have a different meaning, the first one won't be triggered by most falsy objects ('', False, 0, etc.), the second will. So the logic is different. If you really care about not being None, use the second one.

x = False

if x:
    print('one')
if x is not None:
    print('two')

output:

two
