hi, soat the moment i am writing an encryption program, i am not quite sure how to use for loops for lists,
my list at the moment is this:
Somewhere in la Mancha, in a
place whose name I do not care
to remember, a gentleman lived
not long ago, one of those who
has a lance and ancient shield
on a shelf and keeps a skinny
nag and a greyhound for racing.

basically i want to convert the character to ASCII (b = 66) but not if it is a space (32), and then separate each integer and add every integer excluding spaces to another variable I have
After p< tangerine is where
i am having trouble, it just ignores my code and stops after this point

Thanks very much, any help/advice will do!

text_file = input(str("Enter the file you want to be Encyrpted"))
        ciphertext_file = input("Enter the file to write the encrypted message out to: ")
#this will find the text file the user has inputter
        apple = open(text_file,"r")
#this puts the text file so it can only be read
        apple =(apple.read())
        n = 0
        number = []
        texting = []
#================================8 Character Key ================================================= 
#while n is less than 8
        while n<8:
#it will convert a random number between 33 and 126 into ascii
            random_number = chr(random.randint(33, 126))
#every time n + 1
#one turn out of 8
            n = n + 1
#the number is put into ascii
            characters = ord(random_number)
#it is put into the number list
#this rounds each of the eight integers in number and divides by 8 and takes away 3
#==================Offset factor====================
        offset_number = round((number[0]+number[1]+number[2]+number[3]+number[4]+number[5]+number[7])/8)-32
#this prints the offset factor
#=============================Task 5=====================================================================
        newString = []
#this is the only part of ascii allowed
        validLetters = "#$%&'()*+,-./:;<=>?@[\]^_`{|}~""#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghiklmnopqrstuvwxyz{|}~"
        space = [' ']
        new = []
        old = []
        x = 0
#this splits the text file into singukar characters from 0 to 1
        chrsplit = [apple[i:i+1] for i in range(0, len(apple),1)]
#this puts into ascii every character
        ascii_conversion = [ord(i) for i in chrsplit]
#this replaces each 32 in the list with a space
        ascii_conversion= "".join(chr(n) for n in ascii_conversion)
        ascii_conversion = textwrap.fill(ascii_conversion, 32)
        banane = 0 
        for ch in ascii_conversion:
            if ch in validLetters:
                tangerine = len(ascii_conversion)
                banane= banane + 1
        guava = []
        p = 0
        conversion = []
        while p<tangerine:
            for z in ascii_conversion:
                if validLetters in ascii_conversion:
                    chars = [ascii_conversion[i:i+1] for i in range(0, len(ascii_conversion ),1)]
                    mylist  = [ord(i) for i in chars]
                    p = p + 1
                elif  x == ' ':

If the code inside the while loops isn't running, it's probably because p is not less than tangerine. Have you checked the values against each other? For example, what is tangerine equal to in a test scenario?

It is equal to the length of the list although I've fixed the problem, somehow ( rather embarrassingly) the code copied itself 3 times so that while loop and the whole code wasn't being read
