在结束程序之前的最终打印语句之后延迟。 在 c 等效项中转储的核心

Question

There is a good amount of delay (~7-8s) after the final print statement before the program ends while running this code.

li = []

for i in range(100000000): # A very huge number
    li.append(i)

print("Done.")

Pypy worked much faster and showed the expected behaviour. Why is this happening?

Answer 1

I cannot reproduce your results!

This was run on Google Colab CPU instance

It is taking 00.000093 seconds for print statement and program to end!

from datetime import datetime as dt
from tqdm import tqdm
start = dt.now()
li = []

for i in tqdm(range(100000000)): # A very huge number
    li.append(i)
print('\n')
print('Time to run:',dt.now()-start)
start = dt.now()
print("Done.")
print('Time after run:',dt.now()-start)

100%|██████████| 100000000/100000000 [00:33<00:00, 3010464.83it/s]

Time to run: 0:00:34.386686
Done.
Time after run: 0:00:00.000093
