Greetings,
Disclaimer: I'm a Python Noob,
so use the code snippets
in this post, at your own risk!
Is this what you're looking for?
def dec(a):
import string
result=''
for x in string.split(a):
result=result+chr(eval(x))
return result
print dec(raw_input("Enter the message to decode: "))
I took raw_input() out of the dec() function and pass the string to the function
as an argument. Or, to assign it to a variable, then pass it:
a=raw_input("Enter the message to decode: ")
print dec(a)
Or, if you want to read the code from a file on disk called code.txt
which has the following code in it:
65 66 67 68
fin=open('code.txt','r)
a = fin.read()
fin.close()
print dec(a)
ABCD
