Cipher Exceeds The 4x4 Grid And Prints Out Wrong Cipher

So i have created this code below to make a 4*(the length of the cipher) grid based on the cipher text they have provided to work with any value up to 80 that is divisible by 4, i

Solution 1:

mygrid has exactly the dimensions you want. You then call

grid2=list(zip(*mygrid))

which transforms mygrid (4x8) into grid2 (8x4), and print the latter. Try

for i in range (len(mygrid)):
     print(mygrid[i])

or, more pythonic:

for l in mygrid:
    print(l)

If you want each sub-list in mygrid to be a list of single characters, rather than a four-character string you can do this with a small modification to your list comprehension:

mygrid = [list(decode[i:i+4]) for i in range(0,len(decode),4)]
        # ^ add call to list
