Lightweight profiling tool to detect performance BottleNecks in Python code.

Project description

Hence the name: bn - BottleNeck. And you know keys B and N are very comfortable to type quickly in a row.

Usage:

bn('loop')
for item in generator:

    bn('rabbit')
    # code of rabbit

    bn('turtle')
    # code of turtle

    bn('loop')

if bn.total > 1.0:
    logging.info(bn)

Result:

TOTAL=22.2632, turtle=20.6403, rabbit=1.6209, loop=0.0020
#
# This config is default in bn>=0.1.5:
# Bn(total_key='TOTAL', format='{key}={seconds:.4f}', sep=', ')

# OR:

22.2632    TOTAL
20.6403    turtle
 1.6209    rabbit
 0.0020    loop
#
# This config is default in bn<=0.1.4:
# Bn(total_key='TOTAL', format='{seconds:>10.4f}    {key}', sep='\n')

Install:

pip install bn

Scope:

# Global "bn" is useful to profile cross-module without passing "bn" explicitly.
from bn import bn
bn.format = custom_format

# Scoped "Bn" is useful to have multiple independent profilers.
from bn import Bn
def action():
    bn = Bn(format=custom_format)
