[英]Run a program from python, and have it continue to run after the script is killed
[英]Call a Function After a Set Time But Continue to Run Code the Program with Python
我想在設定的時間后調用 function,但繼續運行 python 程序。 這可能嗎?
示例用例:
使用以下代碼,我想在 2 天后調用 function happy_birthday 但在此之前不斷打印Not your birthday
。
def happy_birthday():
print("Happy Birthday")
exit()
[MISSING CODE THAT CALLS happy_birthday]
while True:
print("Not your birthday!")
您正在尋找threading.Timer
。
這會在特定時間后調用一個方法作為線程。
我假設您想在happy_birthday
中使用exit()
退出程序? 您可以通過將條件(變量run
)設置為False
來做到這一點。
import threading
import time
run = True
def happy_birthday():
print("Happy Birthday")
global run
run = False
t = threading.Timer(60 * 60 * 24 * 2, happy_birthday)
t.start() # after 2 day, happy_birthday will be called
while run:
print("Not your birthday!")
time.sleep(.1)
Output
Not your birthday!
Not your birthday!
...
Not your birthday!
Happy Birthday
