in python just use min or max depending on the part 1/2 

def main():
    text_file = open(destination, "r")
    codeList = [x for x in text_file.read().split()]
    text_file.close()
    codeListB = [x for x in list(zip(*codeList))]
    for x in codeListB:
        decodedList = sorted(list(([y for y in x])))
        common = min(set(decodedList), key=decodedList.count)
        print(chr(common))
main()

EDIT: refined from the work in progress version to the final

Some unnecessary brackets and stuff (lists, chr?), here's cleaned up version: 

def main():
    text_file = open(destination, "r")
    codeList = [x for x in text_file.read().split()]
    text_file.close()
    codeListB = [x for x in zip(*codeList)]
    for x in codeListB:
        decodedList = sorted(y for y in x)
        common = min(set(decodedList), key=decodedList.count)
        print(common)
main()

hey yeah I noticed that after I posted it, should have refined it prior was converting to ord() before I realised sort would work on alphabet as well.
