You can add the following line anywhere in your code to start a pudb breakpoint:
import pudb; pudb.set_trace()
You can also press `b` in pudb to add a breakpoint with a keyboard shortcut.
The standard pdb docs should work for pudb with one small exception.
At the programming language level, PuDB displays the same interface as Python���s built-in pdb module. Just replace pdb with pudb. (One exception: run is called runstatement.)
