Program on String Functions.

Understanding string functions. 

 

isalnum() - returns True if character is alphabet or number.

in a string, returns True if string contains only letters and alphabets.

                    returns False if string contains special characters.

                    string="abg1234".isalnum()    #returns True

                    string="abg12@#$34".isalnum()    #returns False

isalpha() - returns True if character is an alphabet.

isdigit() - returns True if character is a number.

islower() - returns True if character is a lower case alphabet.

isupper() - returns True if character is a upper case alphabet.
