The Python debugger allows you to step through your code and identify any performance issues. Use it to find bottlenecks and optimize your code. Example:

The example code shows how to use the Python debugger (pdb) to optimize a function. The pdb.set_trace() statement is placed inside the loop to break into the debugger at each iteration. This allows us to inspect the variables and the code flow at each iteration, and identify any performance bottlenecks or bugs in the code.
