What is Python debugging?
The Python debugger is an interactive source code debugger for Python programs. It can set conditional breakpoints and single stepping at the source line level. It also supports inspection of stack frames, source code listing, and evaluation of arbitrary Python code in any stack frame’s context.
How do I start debugging in Python?
Execute the statement (given as a string or a code object) under debugger control. The debugger prompt appears before any code is executed; you can set breakpoints and type continue , or you can step through the statement using step or next (all these commands are explained below).
Is debugging easy in Python?

What are the types of debugging in Python?
Some common debugging techniques include:
- Printing out or displaying values of variables and state at certain times during the execution of an application.
- Changing the state of a program to make it do different things.
- Stepping through the execution of a program line by line.
- Breakpoints.
- Trace Points.
What is the best way to debug Python?
Some useful ones to remember are:
- b : set a breakpoint.
- c : continue debugging until you hit a breakpoint.
- s : step through the code.
- n : to go to next line of code.
- l : list source code for the current file (default: 11 lines including the line being executed)
- u : navigate up a stack frame.
- d : navigate down a stack frame.

When you run a Python script, the interpreter converts a Python program into something that that the computer can understand. Executing a Python program can be done in two ways: calling the Python interpreter with a shebang line, and using the interactive Python shell .
