pudb is a great GUI debugger. It uses commands from pdb like u (up) and d (down) to move around a call stack and n to process a single step. A cool feature of pudb debugger is the prompt on the last line of your code to restart debugging.
Quick start commands:
|ctrl-p||Preferences. Change colour themes etc.|
|ctrl-l||Redraws screen. Useful after changing preferences.|
|!||Go to the command line.|
|ctrl-x||Exit from command line.|
# Run inline using set_trace() (see the figure) # vowels.py is exactly the same script used for pdb debugger. python vowels.py # Run at command line pudb vowels.py
Make sure to have appropriate privileges if running the second option (i.e. sudo pudb vowels.py). pudb will exit to a post-mortem screen if you don't. Also, use s to step into functions rather than using n.
EDIT: On further testing I noted several points. First, if you try to run this inside a python notebook you won't get very far, it will break. Second, if you include a raw_input command (input for py3x), the GUI will temporarily disappear so you can enter a string in the terminal.
