Python code speed analyzer.
Monitor the performance of your scripts etc. tools and understand where time is spent.
It's a Python library, what do you expect?
pip install pyhaste
# OR
poetry add pyhasteTo measure your code, pyhaste exports a measure context manager, give it a name as an argument. Once you want a report call report from pyhaste.

In case you need more complex analysis, you might benefit from pyhaste.Analyzer and creating your own instances, e.g. for measuring time spent on separate tasks in a longer running job:
import time
from random import uniform
from pyhaste import Analyzer
for item in [1, 2, 3]:
analyzer = Analyzer()
with analyzer.measure(f"process_item({item})"):
with analyzer.measure("db.find"):
time.sleep(uniform(0.04, 0.06) * item)
with analyzer.measure("calculate"):
with analyzer.measure("guestimate"):
with analyzer.measure("do_math"):
time.sleep(uniform(0.1, 0.15) * item)
with analyzer.measure("save"):
time.sleep(uniform(0.05, 0.075) * item)
time.sleep(uniform(0.01, 0.025) * item)
