Visualize the execution of Python code using www.pythontutor.com

Online Python Tutor (www.pythontutor.com) is a free educational tool created by Philip Guo (www.pgbovine.net) that 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.
