How to debug Python programs?

When we can’t understand the execution path or behaviour of our program we better use a debugger. Python offers pdb, a full featured debugger. Here is how to get started.

Import it with:

import pdb 

Set a breakpoint with:

pdb.set_trace()
# The script execution will then stop
# and let you debug.

You can also trace full program with:

python -m trace --trace my_program.py
