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
