Examine exception from interpreter	jupyter notebook 'debug'
Pinpoint variables in scope	import IPython; IPython.embed()
Pinpoint variables in scope	import code; code.interact(local=locals())
Pinpoint variables in scope	whos
Set breakpoint	import pudb; pudb.set_trace()
Run with debugger	pudb – xyz.py arg1 arg2
Start debugger on CTRL-C	import
Start debugger on CTRL-C	pudbpudb.set_interrupt_handler()
Trace threads	import wdb; wdb.set_trace()
