Python Debugging Tips presented at PyCon Asia Pacific 2016 in Seoul, South Korea. Please see below for slides.

1. Examine exception while running interpreter

jupyter notebook
debug

2. Pinpoint variables in scope

import IPython; IPython.embed()
whos

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
