Python Tutor is an online single-step debugger meant for novices. You can put in code on the edit page then click "Visualize Execution" to start it running.

Among other things, it supports:

• live help from volunteers (which is great for newbies)
• setting breakpoints
• hiding variables
• saving/sharing
• a few other languages like Java, JS, Ruby, C, C++

However it also doesn't support a lot of things, for example:

• Reading/writing files - use io.StringIO and io.BytesIO instead: demo
• Code that is too large, runs too long, or defines too many variables or objects
• Command-line arguments
• Lots of standard library modules like argparse, csv, enum, html, os, struct, weakref...
