About Python Tutor
Python Tutor lets you write code in a web browser and watch what happens line by line as it runs. It draws variables, objects, pointers, data structures and stack frames, so you can see how memory and references change at each step.
Despite the name, it supports Python, Java, C, C++ and JavaScript. Students use it to debug homework, teachers use it to explain concepts in class, and programmers use it to prepare for interviews. It has been running since 2010 and is used in courses at many universities.
