How to use the Python debugger (pdb)

To use the Python Debugger (PDB) in Python, you can follow these steps:

1. Insert a breakpoint in the code: Insert a breakpoint at the location in the code where debugging is needed. This can be achieved by inserting import pdb; pdb.set_trace() in the code, which will launch the PDB debugger at that specific location.
2. Run your program and enter debug mode: Execute your Python script in the terminal. When the script reaches a point with pdb.set_trace(), the program will pause and the PDB debugger will start.
3. PDB command:
4. Once you enter the PDB debugger, you can use a variety of commands to control the program’s execution and view variable values.
5. Some common PDB commands include:
   n: Execute the next line of code. c: Continue executing until the next breakpoint or program ends. s: Step through the current line. q: Quit the debugger. p : Print the value of a variable. h: Get help information, etc.
6. Navigate in the PDB:
7. You can debug line by line in the code, view variable values, and control the execution flow of the program using PDB commands.
