Reference: Logging and Debugging

Quick-lookup pages. Short, dense, and designed to skim — the sort of thing you keep a tab open on while you're working through a logging config or a debugging session. If you're here to learn the topic for the first time, start with Learn instead.

Pages in this section

• logging module quick reference — loggers, handlers, formatters, and the methods you actually use day-to-day.
• Log format reference — every %(name)s-style directive you can drop into a format string, with examples.
• pdb commands reference — the full command list for an interactive debugging session, grouped by what you're trying to do.
