Hi. I'm new to this Python language and I've been doing this project for the last two weeks:

Write an n-stepped encryption program.

This is a little different from what I told you in class, so follow these instructions.


The user should be able to set the number of steps that the encoding algorithm uses.

The program should only encrypt upper-case letters, spaces and numbers (any other character in the message should remain unencrypted).
The user should create a text file with an unencrypted message. The program should create a second text file, which is the encrypted message.



Coding Steps:

1. write a function encrypt that takes in a string and a step and implements an n-step encryption algorithm, returning the result
2. write a load function, that reads in all the data in a file
3. write a write function, that writes a string to a file
4. Write a program flow based around these functions
5. Write a program, using functions 1 through 3, to accomplish the assignment.

AND I'M STILL EXPERIENCING PRBLEMS.This is what I've come up with so far:

def read():
a=open("news.txt","r")
text=a.read()
a.close
return text
print


def encrypt(string,n):
result=[]
for char in string:
x=ord(char)
x+=2
result.append(chr(x))
return str(result)

def write(string):
b=open("output.txt","w")
b.write(string)
b.close()
string=[]
write(string)
Can someone please help me. It's due on Monday.

Sorry I didn't get to this until it was "too late". You made a good effort, so I'm willing to show you how I would've done it:

import string
encryptable = string.ascii_uppercase + string.digits + string.whitespace

def read(path):
    f = open(path,"r")
    text = f.read()
    f.close()
    return text

def encrypt(s, step=1):
    result=[]
    for c in s:
        if c in encryptable:
            x = ord(c) + step
            result.append(chr(x))
        else:
            result.append(c)
    return ''.join(result)

def write(path, s):
    f = open(path,"w")
    f.write(s)
    f.close()

Let me know if you still need help or don't understand anything here, or if you'd like a more thorough analysis of anything.
