Problem 5_of_higher_level.py

#q no.5 .Given two strings as input, find out if these are the same or not (allowing for maximum one mismatch).
def string_same_check(strg1, strg2):
    '''Fiirstly we should check whether the length of
       both the taken input string is same or not then check character  .
       Examples:
       >>> string_same_check('swati' ,'swate')
       'same'
       >>>string_same_check('Bhaiya' , 'Bhaiji')

       Returns:
         'same' :if atmost one mismatch in stg1 and strg2.
         'not same' : if more than one mismatch in strg1 and strg2.
