This is a common issue, you are presumably importing your
program rather than using IDLE's save/run feature? If so you

This second definition overrides the first - you cannot do
function overloading based on parameters in Python.

These just create instan
So from the answers, i want to imagine how python exercise the codewhen you push the button execute. My guess before looking at the docsor other material,1. check python syntax
2. transform to byte code.3. execute the byte code.

Is there a method in Python like this
already:

Have a look at the datetime module: if date1 and date2 are both
datetime.date instances, then (date1-

Hi,
Check the datetime module, it will give you distance between dates in
the units you specify. It is included in the standard dis
What's the invalid syntax?
[code]
from datetime import *
def menu(): print "(A)dd days
to current date." print "(F)ind how many days have passed
since a date." print "(E)xit."
def menu_choice(): choice =
raw_input("Enter the letter of your choice: ") return
choice

Ignore this. I've created too many errors to even
begin to solve.

I don't know, what did python tell you when you tried to run the code?

Look at the datetime module it has methods for getting differences in
daes/times etc.

What you have is correct for a main program.

I am working out of How To Think Like A Computer

queues. Here is some code that creates a linked queue
class:
class Queue:

self.length = 0
self.head = None
def isEmpty(self):

After reading John's reply, I think I get it now:
>>> from linked_queue import *
>>> queue = Queue()
>>> queue.isEmpty()
True
>>> queue.insert("cargo")
>>> queue.length
1
>>> queue.insert("more cargo")
>>> queue.length
2
>>> print queue.head
cargo
>>> print queue.head.next
more cargo
>>> queue.ins
