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

I am working out of How To Think Like A Computer
Scientist. I am on the chapter that covers linked
queues. Here is some code that creates a linked queue
class:
class Queue:
def __init__(self):
self.length = 0
self.head = None
def isEmpty(self):

What you have is correct for a main program.

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

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

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

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.

This second definition overrides the first - you cannot do
