Most of the Python developers reading this book might already be aware of the usage of python debugger (pdb). For those who are not aware of it, pdb is an interactive source code debugger for Python programs. We can set breakpoints wherever needed, debug using single stepping at the source line level, and inspect the stack frames.

In this recipe, let's have a look at what pdb brings to the table.
