How do you debug in Python?

In Python, there are various methods available for debugging code. Here are some commonly used methods:

1. Use the print statement: insert print statements in the code to output the values of variables, in order to observe the execution process of the program and the values of the variables. This method is simple and straightforward, suitable for simple debugging tasks.
2. Use breakpoints: Insert breakpoints in the code by adding the statement import pdb; pdb.set_trace() where you want the program to pause execution. When running the program, it will pause and enter debugging mode when reaching this statement, allowing you to execute the code line by line and check variable values.
3. Many integrated development environments (IDEs) offer debugging features, such as setting breakpoints, step-by-step execution, and viewing variable values. Powerful debugging capabilities can be found in IDEs like PyCharm and Visual Studio Code.
4. Debugging in Python: Python comes with a built-in debugger module called pdb, which allows debugging using the pdb debugger in the command line. You can run a script and enter the pdb debugger by using the command python -m pdb script.py. In debugging mode, you can use various commands to control program execution, view variable values, and more.
5. Using third-party debuggers: In addition to Python’s built-in debugger, pdb, there are also other third-party debuggers available such as ipdb and pycharm. These debuggers offer more features and convenience, allowing you to choose based on your needs.

Here are some common Python debugging methods, you can choose the appropriate method based on the specific situation.
