How do I debug using pdb

PDB (Python Debugger) is a powerful tool that allows developers to debug their Python code efficiently. Below is a brief guide on how to use PDB along with an example.

Getting Started with PDB

To start debugging with PDB, you need to insert the following code in the part of your code where you want the debugger to begin:

import pdb; pdb.set_trace()

Basic Commands in PDB

  • n - Goes to the next line within the same function.
  • s - Steps into a function call.
  • c - Continues execution until the next breakpoint.
  • q - Quits the debugger.
  • p - Prints the value of an expression.

Example of Using PDB

Here's a simple example demonstrating how to use PDB in a Python script:

def faulty_function(x): import pdb; pdb.set_trace() # Start the debugger y = x * 2 z = y / 0 # This will cause a ZeroDivisionError return z result = faulty_function(5) print(result)
