string_find_mismatch.py

#Write a function named find_mismatch that accepts two strings as input arguments and returns:

# 0 if the two strings match exactly.
# 1 if the two strings have the same length and mismatch in only one character.
# 2 if the two strings do not have the same length or mismatch in two or more characters.
#Capital letters are considered the same as lower case letters. Here are some examples:
#First string	    Second String	Function return
# Python	    Java	        2
# Hello There	    helloothere	        1
# sin	            sink	        2 (note not the same length)
# dog	            Dog	                0
