What is one effective debugging tool available in Python?

The Python Debugger, commonly referred to as pdb, is an effective debugging tool specifically designed for Python programming. It allows developers to set breakpoints, step through code line by line, inspect variables, and evaluate expressions at runtime. This interactive debugging experience helps in identifying and resolving issues in the code efficiently.

pdb is integrated into Python's standard library, meaning it is readily available without the need for additional installations. By using pdb, programmers can delve deeper into their code's execution flow, which aids significantly in troubleshooting and understanding complex code behavior.

While other choices like IDEs (such as PyCharm) and environments (like Jupyter Notebook) provide various debugging capabilities through graphical interfaces, pdb stands out for its simplicity and immediate accessibility through the command line, making it a fundamental tool for Python developers.
