#40885 — crypto program in python.

Hi every every body,
Today I have to submit my assignment for Computer Science, And I am absolutely stuck in writing the code. Please help me in soon possible.

The main idea of the program is encode and decode the text.
that wot the instructor gave us so far.

Sample Run

Here's a sample run of the basic program in action.

  SECRET DECODER MENU
  
  0) Quit
  1) Encode
  2) Decode
  
What do you want to do? 1
text to be encoded: python rocks
AQULEWKEMNJ

  
  SECRET DECODER MENU
  
  0) Quit
  1) Encode
  2) Decode
  
What do you want to do? 2
code to be decyphered: AQULEWKEMNJ
PYTHONROCKS

  
  SECRET DECODER MENU
  
  0) Quit
  1) Encode
  2) Decode
  
What do you want to do? 0
Thanks for doing secret spy stuff with me.
-----------------------------------
and


alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
key =   "XPMGTDHLYONZBWEARKJUFSCIQV"

def main():
  keepGoing = True
  while keepGoing:
    response = menu()
    if response == "1":
      plain = raw_input("text to be encoded: ")
      print encode(plain)
    elif response == "2":
      coded = raw_input("code to be decyphered: ")
      print decode(coded)
    elif response == "0":
      print "Thanks for doing secret spy stuff with me."
      keepGoing = False
    else:
      print "I don't know what you want to do..."

-------------------

I am confused about menu and the str function if you can help me with this code it will be awesome thank you!!!

I believe your instructor intends you to start with the skeleton
of the program provided above. Complete it by writing the missing
functions: menu, decode, and encode.

that is where I confused, I am not sure how to do it, I started but nothing works. And the tutorials at the internet not helpful. If you could write me the code for the decode function, that would be awesome, and other i can do by myself.

thanks

Thanks for being honest. But I cannot agree to write any code for
you.

Can you post an example of something you tried that didn't work?

print (' SECRET DECODER MENU')
print ('     1) Encode')
print ('     2) Decode')
print ('     3) Quit')

response = raw_input (" What do you want to do? ")
print response

import alpha

def menu():
  while response is "1" or "2" or "3":
    if response not in ('1', '2', '3'):
      print ("I don't know what you want to do...")
      continue

First, think about how to do this without writing code.

alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
key =   "XPMGTDHLYONZBWEARKJUFSCIQV"

The example shows "python rocks" being turned into
AQULEWKEMNJ

Do you see from the two strings how that works?  If you can see that, write
a description of how you encode a message.  Bring that back with some code
that does the same and you will get help
