LBLProf

LBLProf is simple a line by line terminal based time profiler. It allows you to track the duration of each line and get a tree of the execution of the code.

It comes with a simple interactive terminal UI to navigate the tree and see the stats of each line. Example of the terminal ui:

Warning

LBLProf is a tool that is based on the sys.monitoring API that is available in Python 3.12 and above. It means that you need to use Python 3.12 or above to use it.

Installation

pip install lblprof

The only dependency of this package is pydantic, the rest is standard library.

Usage

This package contains 4 main functions:

• start_tracing(): Start the tracing of the code.
• stop_tracing(): Stop the tracing of the code, build the tree and compute stats
• show_interactive_tree(min_time_s: float = 0.1): show the interactive duration tree in the terminal.
• show_tree(): print the tree to console.

from lblprof import start_tracing, stop_tracing, show_interactive_tree, show_tree

start_tracing()

# Your code here (Any code)

stop_tracing()
show_tree() # print the tree to console
show_interactive_tree() # show the interactive tree in the terminal

How it works

LBLProf is based on the sys.monitoring API that is available in Python 3.12 and above. PEP 669

This new API allow us to cut down tracing when we are entering installed package and limit the tracing to the code of the user.
