Says Name Error: global name 'string' is not defined. How do I correct?

def main():

 

    print "This program converts a sequence of ASCII numbers into"
    print "the string of text that it represents."
    print

    # get the message to encode

    instring = raw_input("Please enter the ASCII-encoded messages: ")
    #loop through each substring and build ASCII message

    message = ""
    for numStr in string.split(inString):
        asciinum = eval(numstr)    # convert digits to a number
        message = message + chr(asciinum)    # append character to message

    print  "The decoded message is: ", message

main()

Replace:

string.split

With:

instring.split

not working, are you able to get it to work?

[Andy Milne]

Fixed the error, but doesn't run as you expect?

What delimiter are you expecting in the input?

Whatever the delimiter is, pass it as the parameter to split.

got these programs out of book python programming introduction to computer science 2004 which could be my problem. The first program: text2numbers.py works fine but it's sister program- numbers2text.py take the numbers and turns them back into legible text. and ive done it exactly as the book shows so thats why im puzzled and thinking its just out of date code. Im in my first year with this so if that gives you an indication as to where im at here.Thanks for helping Im just glad someone replied!
