Python File I/O Assignment headache

Hey Trip!

Found what the problem was immediately, but will leave you to read the code to deduce what it is. ;)

The problem with your code or mine?

The error message for the code that I posted.

Ok. Thanks. I'll let you know when I have it sorted.

The part of the program defining how option 4 should lookup an existing name and number should be written as follows:

def lookUpdetails(name):
    '''
    Retrieves details for 'name'
    if they exist.
    '''
    
    global number
    
    if not number.has_key(name):
        print "Key doesn't exist."
    else:
        print "Name: %s and Number: %s" % (name, number[name])

In the original program, the word number which I have bolded is actually written as key. I think you just looked at "if not number.has_key(name)" and focused on "key(name)".

I made the change and tested the program. It works now. I guess there's hope for me yet.

I'll just attach the program I'm working on right now (the I/O program) because it's pretty long. I'm posting the specific area that I'm trying to figure out here:

'''After print >> out_file, there must be a string listed...not a dictionary. What do I put there?'''

def save_grades():
    out_file = open(filename, "w")
    print >> out_file, '''what string goes here?'''
    out_file.close()

I'm attaching it as a txt file since the CF forum software won't recognize the .py extension.

some ideas to investigate. your tutorial text should have provided some of these examples.
