使用time . sleep ()

from time import sleep
sleep(0.05)

使用time . sleep ()

from time import sleep
sleep(0.05)

有一个叫做“时间”的模块可以帮助你。我知道两种方法:

sleep Sleep (reference) asks the program to wait, and then to do the rest of the code. There are two ways to use sleep: import time # Import whole time module print("0.00 seconds") time.sleep(0.05) # 50 milliseconds... make sure you put time. if you import time! print("0.05 seconds") The second way doesn't import the whole module, but it just sleep. from time import sleep # Just the sleep function from module time print("0.00 sec") sleep(0.05) # Don't put time. this time, as it will be confused. You did # not import the whole module print("0.05 sec") Using time since Unix time. This way is useful if you need a loop to be running. But this one is slightly more complex. time_not_passed = True from time import time # You can import the whole module like last time. Just don't forget the time. before to signal it. init_time = time() # Or time.time() if whole module imported print("0.00 secs") while True: # Init loop if init_time + 0.05 <= time() and time_not_passed: # Time not passed variable is important as we want this to run once. !!! time.time() if whole module imported :O print("0.05 secs") time_not_passed = False

你也可以使用Timer()函数来实现。

代码:

from threading import Timer

def hello():
  print("Hello")

t = Timer(0.05, hello)
t.start()  # After 0.05 seconds, "Hello" will be printed

使用time . sleep ():

import time
time.sleep(50 / 1000)

请参阅Python文档:https://docs.python.org/library/time.html#time.sleep

请注意，如果你的睡眠时间恰好是50毫秒，你就无法达到这个效果。它只是关于它。
