python calculate time of function code example

Example 1: how to time a python script

from datetime import datetime
start = datetime.now()
# some kind of code
print(datetime.now() - start)

Example 2: how calculate time in python

import time
start = time.process_time()
# your code here    
print(time.process_time() - start)

Example 3: 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 4: using python how to calculate the time

import time

# starting time
start = time.time()

# program body starts
for i in range(10):
    print(i)

# sleeping for 1 sec to get 10 sec runtime
time.sleep(1)

# program body ends

# end time
end = time.time()

# total time taken
print(f"Runtime of the program is {end - start}")
