def remove(file): punctuation = string.punctuation for ch in file:

    if len(ch) > 1:

        print('error - ch is larger than 1 --| {0} |--'.format(ch))

    if ch in punctuation:

        ch = ' '

        return ch
    else:
        return ch

ref = (open("ref.txt","r"))

test_file = (open("test.txt", "r"))

dictionary = ref.read().split()

file = test_file.read().lower()
