Time Consumption of Abusing Python List Deduction

Clone this repository, and run these scripts:

$ python3 test1.py
$ python3 test2.py

And see the differences?

test1.py

from test_functions import *

results = test_for_n_times(10, func_1)

print_results(results)

test2.py

from test_functions import *

results = test_for_n_times(10, func_2)

print_results(results)

test_functions.py

import time

s = ''
N = 1000000

def func_1():
    [ print(s, end='') for i in range(N) ]


def func_2():
    for i in range(N):
        print(s, end='')


def test_for_n_times(n, foo):
    for i in range(n):
        st = time.time()
        foo()
        yield (time.time() - st)

        
def print_results(l):
    l = list(l)
    for val in l:
        print('\t{:.3f}'.format(val))
    print('Avg:\t{:.3f}'.format(sum(l)/len(l)))
