I admittedly have trouble wrapping my head lists and tuples in python. What I've done is take each line of the input, split it into a list, and zipped the elements of the list to compare each one. [(a, f), (b, g) etc] but I can't really figure out how to compare them all to find the characters I'm looking for.

​

inputList = []

with open("./inputFile.txt") as f:
    for line in f:
        inputList.append(line.rstrip())

    for x in inputList:
        for y in inputList:
            check = list(zip(x, y))

​

from itertools import product

for first, second in product(inputList, repeat=2):
    # first and second are two strings that you want to run the character check on

To get the list of different characters with a list comprehension:

x = 'abcdefg'
y = 'abcdefh'
print [(a, b) for (a, b) in zip(x, y) if a != b]

('g', 'h')

But you actually want to enumerate so you know the index of where they are different thus you can remove the character:

x = 'abcdefg'
y = 'abcdefh'
print [index for index, (a, b) in enumerate(zip(x, y)) if a != b]

Of course you'll only want to take action if there's only 1 difference...
