notes: only file editor, you can change the drop down box value to "show only outputs" if there is any output, has Python versions 2 and 3
LEARN programming by visualizing code execution
Helps students overcome a fundamental barrier to learning programming: understanding what happens as the computer executes each line of a program's source code. Using this tool, a teacher or student can write a Python program in the Web browser and visualize what the computer is doing step-by-step as it executes the program.
try:
Write: Python 2.7 code here or load an example:
    name = raw_input('What is your name?\n')
    print 'Hi, %s.' % name
Program Output:
    What is your name?
    Name1
    Hi, Name1.

What is duck typing?
  It is a term used in dynamic languages
that do not have strong typing.
  The idea is that you don't need a type
in order to invoke an existing method on an object -
if a method is defined on it, you can invoke it.
  The name comes from the phrase
"If it looks like a duck and
quacks like a duck,
it's a duck".
