There were a few issues with your code...

1.Remove -1 from len(letters)

2.Move back one indent and do b = b + 1 even if you don't go into the if statement

3.Indent and do a = a + 1 in the first for loop.

See below of how to fix your code...

    letters = 'acbdc'
    for a in range(0, len(letters)):
        # print(letters[a])
        for b in range(0, len(letters)):
            # print(letters[b])
            if (letters[a] == letters[b]) and (a != b):
                print(b)
            b = b + 1
        a = a + 1
