Timeit module

[snippsat]

One of the simplest way beside %%timeit cell magic,is just to put all in string.

import timeit

np_test = '''\
import numpy as np

NUM_ELEMS = 10
SCALE = 1000
s1 = set( (np.random.rand(NUM_ELEMS) * SCALE).astype('int') )
s2 = set( (np.random.rand(NUM_ELEMS) * SCALE).astype('int') )
s1.intersection(s2)
'''

print(timeit.Timer(stmt=np_test).timeit(number=100000))

Output:
