## What it is
snoop is a Python debugging library that traces function execution via a decorator, logging which lines ran and how local variables changed. It is a more featureful fork of PySnooper and also includes an enhanced print-debugging tool (pp) similar to icecream.

## Use cases
- debug why my python function returns wrong values
- trace which lines of code executed and when variables changed
- replace scattered print statements with one decorator
- see a play-by-play log of a function's execution
- debug code in jupyter notebooks
- print variable values with source expressions
- trace subexpression values in an expression

## When to choose
- you want quick line-by-line execution tracing without setting up a debugger
- you can't or don't want to use breakpoints (e.g. long-running scripts, servers)
- you want richer output than PySnooper or icecream provide
- you work in IPython/Jupyter and want integrated tracing

## When to avoid
- you need a full interactive debugger with breakpoints and stepping
- you need a debugger attached to an IDE with visual inspection
- tracing overhead is unacceptable in performance-critical production code

## Facets
- artifact type: library
- maturity: active
- function: logging, developer-tools
- domain: developer-tools, testing
- platform: python, cross-platform
- tags: debugging, print-debugging, tracing, pysnooper, decorator
