Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence.

>>> print 'ab123'.isalnum() True >>> print 'ab123#'.isalnum() False
str.isalpha()
This method checks if all the characters of a string are alphabetical (a-z and A-Z).
>>> print 'abcD'.isalpha() True >>> print 'abcd1'.isalpha() False
str.isdigit()
This method checks if all the characters of a string are digits (0-9).
>>> print '1234'.isdigit() True >>> print '123edsd'.isdigit() False
str.islower()
This method checks if all the characters of a string are lowercase characters (a-z).
>>> print 'abcd123#'.islower() True >>> print 'Abcd123#'.islower() False
str.isupper()
This method checks if all the characters of a string are uppercase characters (A-Z).
