boolean from a function

Show all headers | View raw

I'm not sure for how long I had this bug, and I could not understand the 
problem.

I had a function which would return a boolean

def func_bool():
     if x:
         return True
     else: return False

Now somewhere else I had

if func_bool:
     # do something

I could not quite understand why it was always true, until I finally noticed
that the () were missing.
Is there some tool to avoid these stupid mistakes? (pylint doesn't warn 
me on that)
I don't think I will ever (or almost) have to use a function as a 
boolean, instead of its return value...
