• Containers with length 0, including but not limited to empty strings, empty tuples, and empty lists
• Objects whose __bool__ method returns False
• Objects whose __len__ method returns 0

Example:

print("0 is", bool(0))
print("10 is", bool(10))
print("'hello world' is", bool('hello world'))
print("'' is", bool(''))
print("None is", bool(None))
