"Online Python Tutor is a free educational tool 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 directly in the web browser and visualize what the computer is doing step-by-step as it executes the program."

This is essentially akin to WinDbg, but for Python plus fancy visuals minus debugging symbols minus OS dependency.
I see how this is useful for those who have no prior programming knowledge. Back in the days, I learned C and C++ by littering my source codes with #define macros, #ifdef, and #endif to print out code execution path, which get really messy very quickly -- Internet was a luxury at the time, so we couldn't just look up something everytime we hit a wall, and there was nothing similar to CodeReview. I ended up learning some Assembly to be more efficient in debugging and to better understand the implication of every single line of code I write.
I like Python, but I haven't got a chance to build real software with it. I do use it for quickly testing ideas in code form and, to a degree, prototyping.
