The line "if int:" is clearly wrong. Did you write this code
yourself, or was it typed in from a listing somewhere? I'd assume that
you wanted to do some check on the char value. But if int will always
be true.

I want it to look in s, and only perform this code on the letters in s(not
numbers):
char_low = s.lower()if char_low<= 'm':dist =
13else:dist = -13
Your formatting is messed up, and I can now see there at least one other
bug in it anyway.
The method to check if a particular character is alphabetic is
str.isalpha(). See if you can see what variable to call that on.
Hint: it's not s, since you want to check one character at a time in
your loop.
