Get time of execution of a block of code in Python 2.7

Question

I would like to measure the time elapsed to evaluate a block of code in a Python program, possibly separating between user cpu time, system cpu time and elapsed time.

Answer 1

I found myself solving this problem again and again, so I finally created a library for it. Install with pip install timer_cm. Then:

from time import sleep
from timer_cm import Timer

with Timer('Long task') as timer:
    with timer.child('First step'):
        sleep(1)
    for _ in range(5):
        with timer.child('Baby steps'):
            sleep(.5)

Output:

Long task: 3.520s
  Baby steps: 2.518s (71%)
  First step: 1.001s (28%)
