What does if False Python mean?
The if False is a way of preventing the code which follows from executing but is bad practice.
Example If false Python
So if False python means that the code under this condition will not run. As this condition is always false, the code of this branch is not executed.
if False: print("Never execute")
Use not Keyword
It will execute the if block code.
var = False if not var: print('stuff')
What is the correct way to check for False?
Answer: if the value could be anything you could check that it’s a boolean and
not: this doesn’t rely on
False being a singleton. If it always is a singleton you can also do:
if somevalue is False
But PEP8 of Python states you shouldn’t care if it about the class and just use:
if not somevalue
this will evaluate if
somevalue is “falsy”. See Python documentation on Truth value testing.
Don’t compare boolean values to True or False using == .
Yes: if greeting: No: if greeting == True: Worse: if greeting is True:
