How to debug in Python?

In Python, there are several common debugging methods that can help us identify the issue.

1. Use the print statement: insert print statements at key points to display the values of variables, in order to observe the program’s execution process.
2. Utilize the pdb module: pdb is a debugger in the standard library of Python, allowing you to insert breakpoints in your code to execute it line by line and inspect variable values. You can start the pdb debugger in command line mode or directly import pdb in your code and use pdb.set_trace() to set breakpoints.
3. Debugging features of IDEs or editors: Many IDEs or editors come with integrated debugging features that allow you to set breakpoints in your code, step through your program line by line, and inspect variable values and the call stack.
4. Utilize third-party debuggers: In addition to pdb, there are other third-party debuggers that can be used, such as PyCharm, Visual Studio Code, which provide more powerful debugging features and user-friendly interfaces.

Utilizing debugging tools can assist us in locating issues more conveniently and speeding up the repair process. Various debugging methods are suitable for different scenarios, allowing individuals to choose the appropriate method based on their preferences and needs.
