Has anyone else tried this? It's a pretty good way to learn python (but it can be done in any language).

Here's a simple script I wrote to open a text file, increment all the letters in it by two and save them to another text file:

CODE

import sys
import string

in_file = open("encrypt", "r")
text = in_file.read()
in_file.close()

def increment(char, by=2): return chr(ord(char)+by)

out_text = ""
for char in text:
    if char.isalpha():
        if char.startswith(("y","z","Y","Z")):
            out_text = out_text + increment(char, -24)
        else:
            out_text = out_text + increment(char)        
    else:
        out_text = out_text + char
    
out_file = open("py.out", "w")
out_file.write(out_text)
