Debugging in Python involves identifying and fixing errors in your code. Python provides several tools and techniques to debug programs effectively, including the built-in pdb module, the breakpoint() function, and online debugging tools.

Using the pdb Module

The pdb module is Python's built-in debugger, offering features like setting breakpoints, stepping through code, inspecting variables, and evaluating expressions. To use pdb, you can insert the following line in your code where you want to pause execution:

Alternatively, starting from Python 3.7, you can use the simpler breakpoint() function:

When the debugger is triggered, you'll see the (Pdb) prompt, allowing you to execute commands like:
