Python - Truthy and Falsy Values

Python tip:

In Python, individual values can evaluate as either True or False. Values that evaluate to True are "Truthy", and values that evaluate to False are "Falsy".

By default, an object is considered Truthy, unless its __bool__() method returns False or __len__() returns 0.

empty_list = []
empty_touple = ()
empty_dict = {}
empty_set = set()
empty_string = ""
empty_range = range(0)

print(bool(empty_list)) # False

print(bool(empty_touple)) # False

print(bool(empty_dict)) # False

print(bool(empty_set)) # False

print(bool(empty_string)) # False

print(bool(empty_range)) # False

print(bool(0)) # False

print(bool(0.0)) # False

print(bool(0j)) # False

print(bool(None)) # False

print((bool(1))) # True

print((bool(" "))) # True
