LOL...I wish making it work was all i needed...hehe, i would have been done long ago,
my teachers mark everything including the quality of docstring...also, they want the summarized codes most of the time which they refer to as 'pythonic', and the closest thing i found on string was isalpha...

Okay, so i made the code... Can someone check what is wrong with it??
Code:
def is_match (puzzle,view):
'''(str,str)>bool
returns true iff puzzle and view match in the place
where the letters are hidden
>>>is_match ('apples','^pp^^^')
True
>>>is_match ('applesbananas','^^^^^^^^^^^^^')
False
>>>is_match ('applesi', '^^^^^^^')
True
>>>is_match ('applesi', '^^^^^^^^')
False
>>>is_match ('apples','^pp^a^')
False
'''
a = 0
if len(view) == len(puzzle):
for i in range(len(puzzle)):
if (puzzle[i] != view[i] and view[i] != HIDDEN):
return False
else:
return False
return True
