Python在n秒后停止线程

Question

How can i stop a thread after 5 seconds? I want to print "Hello World" every seconds and then stop after 5 seconds. This is my code:

import threading

def printthis():
   threading.Timer(1.0, printthis).start()
   print("Hello, World!")

printthis()

Answer 1

How about this:

def printthis():
    print_count = 0
    while print_count < 5: # 5 because print_count will be 5 after printing the 5th time
        threading.Timer(1.0, printthis).start()
        print("Hello, World!")
        print_count += 1 
printthis()
