Basic usage of the Python debugging module pdb.

The Python debugging module pdb (Python Debugger) is a built-in standard library in Python that can be used for debugging programs. Here are the basic usage of pdb:

1. Import the pdb module:

import pdb

1. Set breakpoints in the program:
   Insert a line of code at the location where breakpoints are needed.

pdb.set_trace()

1. Run the program:
   While running the program, when encountering pdb.set_trace(), the program will pause and enter the pdb debugging environment.
2. Debugging commands:
   In the pdb debugging environment, the following commands can be used for debugging:

1. Use “h” or “help” to view the help information.
2. l or list: display the source code around the current line.
3. n or next: execute the next line
4. s or step: enter the function’s inner scope.
5. r or return: execute the current function and return to the caller.
6. c or cont: continue running the program until the next breakpoint or the program ends
7. q or quit: exit debugging

1. Can you please rephrase that in English?

p variable_name

1. Can you please summarize this in your own words?

!variable_name = new_value

1. Can you please explain the new guidelines in more detail?

The above is the basic usage of pdb. By setting breakpoints and using debugging commands, you can check the values of variables during program execution, locate issues, and debug.
