So you think you can PDB?
summary
Practical walkthrough of using PDB: how to drop into a running program with import pdb; pdb.set_trace(), or start a script under the debugger with python -m pdb; core commands covered include next/step/return/continue, listing and longlist, printing with p/pp, navigating frames with where/up/down, and managing breakpoints including conditional breakpoints. Notes limits (cannot step into C extensions), tricks to avoid name-command collisions (!prefix), and alternatives like ipdb, remote-pdb, and pdb++ with sticky mode.
