print("Boolean of [0] is: ", bool(value))
value = 0
print("Boolean of 0 is: ", bool(value))
value = 1
print("Boolean of 1 is: ", bool(value))
value = -1
print("Boolean of -1 is: ", bool(value))
value = None
print("Boolean of None is: ",bool(value))
value = True
print("Boolean of True is: ", bool(value))
value = False
print("Boolean of False is: ", bool(value))
value = 'a string'
print("Boolean of a string is: ", bool(value))
Output
Boolean of [0] is: True
Boolean of 0 is: False
Boolean of 1 is: True
Boolean of -1 is: True
Boolean of None is: False
Boolean of True is: True
Boolean of False is: False
