There are several debuggers for Python including the pdb
module in the standard library and the "graphical" one in IDLE.

I don't know of a debugger for the bytecode.
There are tools to generate it for a specific function so you can
see what it looks like, but I don't know of any that can dynamically
monitor execution.

The profiler can also tell you what was executed after the fact.

This is an unusual request can I ask why you need to do that?
