这是一个非常基本的解决方案,使用了一个标志

press_been_run = False

def press():
    print("hello world")
    global press_been_run
    press_been_run = True

press()

if press_been_run:
    print("printed")
英文:

This is a very basic solution by using a flag

press_been_run = False

def press():
    print("hello world")
    global press_been_run 
    press_been_run = True

press()

if press_been_run:
    print("printed")
