Not a library but an easy way to do what you want:
string_a="ABCD"
string_b = 'ADCT'
print ([ind for ind,char in enumerate(string_a) if string_b[ind] != char])
[1, 3]
enumerate
gives you the index of each char through the string, if string_b[ind] != char
checks if the chars at corresponding indexes are not the same.
string_b
will have to be the same length or shorter than string_a
or you will get an index error
.
zip
will work for uneven length strings:
[ ind for ind, tup in enumerate (zip(string_a,string_b)) if tup[0] != tup[1]]
