Not all variables can take numerical values for themselves. The boolean data type in python consists of two value i.e. True or False. Bool ( ) generally accepts one parameter, which on testing procedure yields True or False output. If no parameter is passed, default output is False in boolean in python.

 >>> print (bool(1))
>>> a = True 
>>> print (a)
>>> print (3>4)       # test if 3 > 4
>>> str1 = "sush"
>>> str1.islower()   #test if string contains lower case


Note the keywords True and False must have an Upper Case first letter. Using a lowercase true returns an error.
