1. Examine exception while running interpreter

jupyter notebook
    debug

2. Pinpoint variables in scope

import IPython; IPython.embed()

 3. Step through execution at breakpoint

import pudb; pudb.set_trace()

4. Drop into debugger without modifying code

pudb -- xyz.py arg1 arg2 

5. Trace on CTRL-C

import pudb; pudb.set_interrupt_handler()

6. Debug threads or Docker containers

import wdb; wdb.set_trace()

7. Use namespaced logger with rsyslog server

logging.getLogger(__name__)

8. Debug tests

pip install pdbpp; py.test --pdb
