Is there any simple way to benchmark python script?

Question

Usually I use shell command time. My purpose is to test if data is small, medium, large or very large set, how much time and memory usage will be.

Any t

Answer 1

Be carefull timeit is very slow, it take 12 second on my medium processor to just initialize (or maybe run the function). you can test this accepted answer

def test():
    lst = []
    for i in range(100):
        lst.append(i)

if __name__ == '__main__':
    import timeit
    print(timeit.timeit("test()", setup="from __main__ import test")) # 12 second

for simple thing I will use time instead, on my PC it return the result 0.0

import time

def test():
    lst = []
    for i in range(100):
        lst.append(i)

t1 = time.time()

test()

result = time.time() - t1
print(result) # 0.000000xxxx
