Livepython is a desktop app that lets you visually trace, in real-time, the execution of a Python program. In addition, it can track changes in global and local variables as your program is running. Livepython meant to give you a quick grasp of a program's execution flow. It's less messy than sprinkling print statements throughout your code and simpler to use than debuggers/profilers.
Livepython can be launched from the command-line as easily as:
livepython [program] [args...]
SPACE: Play/pause the program.
Left/Right Arrow: Change speed of execution.
V: Open/close Variable Inspector.
npm install livepython -g
