What is Python PDB?

According to the definition of PDB in the Python document, it is a module that provides an interactive source code debugging function for Python programs. The main features (feature) include:

Conditional breakpoint

Single-step debugging of source code at line level

View stack fragments

Evaluate arbitrary code in the context of arbitrary stack fragments (similar to GDB)

Code list

Other

Use Python PDB for simple debugging

The Python program can also achieve a single-step debugging function similar to cAccord +, while the debug module PDB in Python is similar to GDB (common commands, etc.) in c, which can be debugged conveniently.

Here is an example (debug_demo.py):

#! / usr/bin/env Python _ debug = True def debug_demo (val): if _ debug: import pdb pdb.set_trace () # introduce the related pdb module if val

If val
