Now I got some problem that I can't explain and fix.
This is my first python module
TimeHelper.py
from datetime import datetime
def fun1(currentTime = datetime.now()):
print(currentTime)
and another is
Main.py
from TimeHelper import fun1
import time
fun1()
time.sleep(5)
fun1()
When I run the Main.py, the out put is
2020-06-16 09:17:52.316714
2020-06-16 09:17:52.316714
My problem is why the time will be same in the result ? Is there any restrict when passing datetime.now() in to default parameter ?
I think I find the answer.
Thanks for @user2864740
So I change my TimeHelper.py to this
from datetime import datetime
def fun1(currentTime = None):
if currentTime is None:
currentTime = datetime.now()
print(currentTime)
and anything work in my expectation.
