Debugging

Debugging is the process of identifying and fixing errors in code. Python provides several debugging tools and techniques. The built-in pdb module is a command-line debugger that allows setting breakpoints, stepping through code, and inspecting variables. Most IDEs (PyCharm, VSCode) provide graphical debuggers with similar functionality. Print debugging (adding print statements) is simple but effective for quick debugging. Logging provides a more structured way to record execution information. Exception handling and proper error messages help identify issues. Debugging techniques include: reproducing the issue, isolating the problem, using breakpoints, examining variable values, and understanding the call stack. Good debugging skills involve systematic problem-solving, understanding the code's expected behavior, and using tools effectively. Knowing how to debug efficiently saves significant time and frustration in development.
