The Python Debugger, commonly referred to as pdb, is a powerful tool for debugging Python programs. It allows developers to set breakpoints, step through code, inspect variables, and evaluate expressions, making it easier to identify and fix bugs in the code.

To start using pdb, you can insert pdb.set_trace() in your code. This line will pause the execution at that point and open the debugger interface, allowing you to interactively debug your program. You can navigate through your code line-by-line, check the values of variables, and execute commands to control the flow of execution ⁴.

Pdb offers a variety of commands for both basic and advanced debugging. Basic commands include setting breakpoints, stepping into functions, and continuing execution. Advanced commands, such as conditional breakpoints and temporary breakpoints, provide more control over the debugging process, which is particularly useful for larger projects ¹².

Overall, mastering pdb can significantly enhance your debugging efficiency and help you resolve issues more effectively.
