Trying to convert alphabet to numbers. An example of what I'm trying to do is convert the word "green" to a list of corresponding number index values: [6, 17, 4, 4, 13] My eventual goal is to use it in a password encrypter thing, where I can convert the letters to numbers, do some math on the numbers so they're still on [0, 25], and then convert those numbers back to letters, so it's mixed up. Here's code of what I've done so far: def lettertonumber(word): flength = len(word) fcodera = "abcdefghijklmnopqrstuvwxyz" fcoderb = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25] fcoderlength = len(fcodera) numkey = [] i = 0 g = 0 while i < flength: # flength is the length of 'word' (in the case of 'green', 5) while g < fcoderlength: # fcoderlength is the length of the alphabet (26) if word == fcodera[g]: # to convert it to the number numkey.append(fcoderb[g]) # fcoderb is a list with [0, 1, 2, 3... 24, 25] for the alphabet g = g + 1 i = i + 1 return numkey word = 'green' numberkey = lettertonumber(word) The output of print(numberkey) is [6]. My question, then, is considering the loops that I have, why am I only getting one iteration of the i loop worth of numbers in numberkey[], when I should be getting as many as the length of the word (so that print(numberkey) outputs [6, 17, 4, 4, 13]) Sorry if my question is phrased poorly or unhelpful, this is my first question! Also sorry for my ignorance with Python -- I just learned it yesterday! Thank you! Continue reading...
