In this quick tutorial, Marakana Python instructor, Simeon Franklin, is going to show you how you can debug your Python applications using the Python debugger, pdb.

Simeon will start off with a quick intro to pdb: what it is, when to use it, and how to launch pdb. Then he’ll jump into a demo of pdb in action.

    If you are inside pdb, and you want to evaluate a line of python code that conflicts with the pdb command, you can precede the python code with an exclamation mark. For example, if you want to show the value of the the variable "list" use:
    (pdb) ! list

    Seems like a pretty medieval way to debug code.  If this the best Python offers?

    Can you link to the the buggy bubble sort code, so that we can follow along at home.

    Thank you for this concise tutorial! I’m ashamed to say this, but I never got through the wall of text in in manual…

    A good introduction, but you say in the video that you cannot create watch points. From Python 2.5 you can do this using the "commands" command. e.g. create breakpoint 1 then enter:

    commands 1
    silent
    print x,y,z
    cont
    end

    Then run the code. Every time the breakpoint is hit the variables x, y, and z will be printed and it will continue running.
