time a function python code example

Example 1: python time a funciton

import time

start = time.time()
print("hello")
end = time.time()
print(end - start)

Example 2: python: measure time code

import time

# Calculate the power of two for a defined range of number
def power_two(my_range):
    return [x**2 for x in range(my_range)]
 
# Measure time
def measure_time(func):
    start = time.time()
    func()               # any specific function to measure
    end = time.time()
    print(end - start)  
    
measure_time(lambda: power_two(10000000)) # lambda permits to pass the argument of our function

Example 3: python time method

from time import sleep, time

start = time()
sleep(2)
print(format(time() - start, '.3f'), 's', sep='') # 2.003s

Example 4: time module in python

import time
seconds = time.time()
print("Seconds since epoch =", seconds)

Example 5: python timer

import time
timer_length = float(input("How many seconds would you like you're timer to be set for? "))
time.sleep(timer_length)
print("Done!")

Example 6: time a function python

Proper answer to timing a loop over a function multiple times
import timeit
timeit.timeit('func_to_time()',globals=globals(),number=1000)
