ItsMyCode |
Python’s
bool() function converts a given value into Boolean(True or False) using the standard truth testing procedure.The syntax of
bool() method is**bool([value])**The
bool() method can take one argument on which the standard truth testing procedure is applied.The parameter is optional for the
bool() function. If you do not pass any value by default, it returns False.The
bool() function returns True if the parameter of the value passed is TrueFalse if the parameter of the value passed is False or if the value is omittedThere are few exceptional cases where the
bool() method returns False. Following are the values:NoneFalse__bool__ () or __len()__ method, returning 0 or False
# Python program to demostrate bool() function
# Returns False as x is False
x = False
print(x, 'is ',bool(x))
# Returns True as x is True
x = True
print(x, 'is ',bool(x))
# Returns False as x is an empty sequence
x = ()
print(x, 'is ',bool(x))
# Returns False as x is an empty mapping
x = {}
print(x, 'is ',bool(x))
# Returns False as x is 0
x = 0.0
print(x, 'is ',bool(x))
# Returns False as x is None
x = None
print(x, 'is ',bool(x))
# Returns True as x is a non empty string
x = 'ItsMyCode'
print(x, 'is ',bool(x))python
Output
False is False
True is True
() is False
{} is False
0.0 is False
None is False
