You should do these steps one at a time. You have code for step 3 but
you haven't finished step 1 yet. If it says create a function then you
need to write something like

def my_function_name():
    random_number = <some code goes here>
    return random_number

Since you haven't done that you haven't done step 1.

Your main function is empty. You're not calling anything from it.

Don't attempt this step until you've got the others sorted.

The main function above is empty (it doesn't do anything). You need to
replace the line that says 'pass' with other lines of code that do
whatever your program is supposed to do.

Here you call the main function but it doesn't do anything since the
function is empty. The code below is not part of your main function.
You probably want to move it in there (in place of the line that says
'pass').

You only need to open the file once in 'w' mode.

You don't need to use 'print' on the lines above since you're writing
to a file and print is for showing things in the terminal. Although
you could use print to write to the file e.g.:

print >> f, myString

If you do that then there's no need to convert the values into strings
with 'str' above.
