How to use debugging in Python?

In Python, you can debug using the following methods:

1. Insert print statements in the code to output the values of variables or specific information at certain locations, in order to monitor the execution of the code.
2. Set breakpoints: in your code, you can set breakpoints to pause the program at specific lines, allowing you to inspect variable values and the flow of code execution. You can use the set_trace function in the pdb module to set breakpoints. At each breakpoint, you can use commands like step (to execute code one line at a time), next (to execute the next line of code), print (to display the value of a variable), etc.
3. Using the debugging tools provided by an IDE: Many integrated development environments (IDEs) offer debugging features that allow you to easily set breakpoints, step through code, and view variable values by simply clicking a button.
4. Utilize the logging module to output debug information to a log file, while being able to control the level of detail with different log levels.

The above are common debugging methods, choose the appropriate method for debugging based on the actual situation.
