How to debug a Python script

1. Use the built-in Python debugger: The Python debugger (pdb) is a powerful tool for debugging Python code. It can be used to step through code, set breakpoints, and inspect variables. To use the debugger, import the pdb module and call the set_trace() function.

2. Use a Python IDE: Integrated Development Environments (IDEs) are specialized programs for writing and debugging Python code. Popular IDEs include PyCharm, Visual Studio Code, and Wing IDE. All of these IDEs provide features such as syntax highlighting, code completion, and debugging tools.

3. Use print statements: Print statements are a simple but powerful debugging tool. By adding print statements to your code, you can see what values variables have at different points in the program.

4. Use a linter: A linter is a program that checks your code for potential errors. It can detect issues such as syntax errors, undefined variables, and type mismatches. This can help you identify and fix bugs before they become a problem.
