find time of run for python code

import time
start_time = time.time()
main()
print("--- %s seconds ---" % (time.time() - start_time))

get time taken to execute python script

from datetime import datetime
startTime = datetime.now()

#do something

#Python 2: 
print datetime.now() - startTime 

#Python 3: 
print(datetime.now() - startTime)

python program running time

#its tricky and so much easy
#python execute time counter
#coded by Luban
import time
start_time = time.time()
while True:
    x = time.time() - start_time
    x = int(x)
    print('Current Time = ',str(x))

python code execution time

# python code execution time -- using wrapper
import time
def exec_time(func):
    def wrapper():
        start_time = time.time()
        result = func()
        elapsed = time.time() - start_time
        return elapsed, result
    return wrapper

@exec_time
def hlw():
    time.sleep(2)
    return "hello"

t, o = hlw()
print(t, o)  # 2.001209020614624 'hello'
