如何在 python 程序中跟踪时间？

Question

I am writing a game using Python and Tkinter and I need to display how much time the player has left.
I need a function to run regularly and update my time_left variable.
I can't use a while loop because my program will be stuck in it forever.
How do I keep track of time here?

Answer 1

To create a game i think you will still need a loop (game loop). Inside that loop, use datetime and timedelta

from datetime import datetime and timedelta

In your game loop, set a condition;

now = datetime.now()
if datetime.now() <= now + timedelta(minutes=How_many_minutes_you_want_to_run_the_game):
    run_the_game
else:
    stop_the_game

Inside that loop you can simply create a variable to store the current time OR final time( datetime.now() + timedelta(minutes=How_many_minutes_you_want_to_run_the_game) - datetime.now() ) which is time remaining.

EXAMPLE:

from datetime import datetime, timedelta
now = datetime.now()
while datetime.now() < (now + timedelta(seconds=2)):
    print(datetime.now())

This code will print the present time for 2 seconds. You can also set some delay(delay of 1 sec) to print time after each second passes.

Answer 2

import time
start = time.time()
end = time.time()
time_consumed=end-start;
time_left=10-time_consumed; 

10 being the time limit. You can you this code to start noting and print the time taken by user
