## What it is
line_profiler is a Python module for line-by-line profiling of functions, with the kernprof script for running profilers. It is the officially maintained continuation of the original rkern/line_profiler project.

## Use cases
- find slow lines in a python function
- profile a python script line by line
- measure per-line execution time of python code
- debug performance bottlenecks in python functions
- run cProfile via kernprof

## When to choose
- you need finer granularity than cProfile's function-level timing
- you want to decorate specific functions and see per-line hit counts and times
- you want a maintained fork of the original line_profiler

## When to avoid
- you only need function-level profiling, where cProfile suffices
- you need whole-program or statistical sampling profiling
- you are profiling non-Python code

## Facets
- artifact type: library
- maturity: active
- function: benchmarking, developer-tools, cli
- domain: developer-tools, performance
- platform: python, cli, cross-platform
- tags: profiling, line-by-line-profiling, kernprof, performance-analysis, python
