Basic Python Programming Help?

In Python 2, which is what the professor was using, 'print' is a keyword and it is treated specially.

In Python 3, which is what you're using, 'print' is no longer a keyword. It's just the name of a built-in function, and like any function its arguments must be given inside parentheses. So where you currently have this:

  print 'Even'

you must use this instead:

  print ( 'Even' )

This is one of a handful of incompatibilities between Python 2 and Python 3. The changes are summarised at http://docs.python.org/py3k/whatsnew/3.0.html The 'print' change is the first on the list.

At the moment, most of the examples and tutorials you'll find are written in Python 2, so if you're using Python 3 you should take a few moments to read that list. That way you'll have a chance of recognising what's going on when you run into one of the things that behaves differently.

Make sure you have your code properly indented, most python errors aris from indentation, make sure its like this:

x = 15

if (x/2)*2 == x:

print 'Even (thats tabbed across)

I have tried that on my version of python and it works when indented.

Good luck programming in python, its a great langague,

The second is done as such: declare a sum variable for each value if it's zero write sum variable and exit loop if it's not add it to the sum variable
