使用time.sleep()：

import time
time.sleep(50 / 1000)

查看Python留档：https://docs.python.org/library/time.html#time.sleep

最佳答案

使用time.sleep()

from time import sleep
sleep(0.05)

请注意，如果你依靠睡眠完全 50毫秒，你不会得到这个。它只是关于它。

你也可以使用pyautogui作为：

import pyautogui
pyautogui._autoPause(0.05, False)

如果第一个参数不是无，那么它将暂停第一个参数的秒，在本例中为：0.05秒

如果第一个参数为无，第二个参数为True，则它将为全局暂停设置休眠，该设置设置为：

pyautogui.PAUSE = int

如果您想知道原因，请参阅源代码：

def _autoPause(pause, _pause):
"""If `pause` is not `None`, then sleep for `pause` seconds.
If `_pause` is `True`, then sleep for `PAUSE` seconds (the global pause setting).


This function is called at the end of all of PyAutoGUI's mouse and keyboard functions. Normally, `_pause`
is set to `True` to add a short sleep so that the user can engage the failsafe. By default, this sleep
is as long as `PAUSE` settings. However, this can be override by setting `pause`, in which case the sleep
is as long as `pause` seconds.
"""
if pause is not None:
time.sleep(pause)
elif _pause:
assert isinstance(PAUSE, int) or isinstance(PAUSE, float)
time.sleep(PAUSE)

您也可以使用Timer()函数来执行此操作。

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

有一个名为“时间”的模块可以帮助您。我知道两种方法：

  1. sleep

    睡眠（参考）要求程序等待，然后执行其余的代码。

    有两种方法可以使用睡眠：

    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")

    第二种方法不导入整个模块，它只是休眠。

    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")

  2. 自unix时间以来的使用时间。

    如果您需要运行循环，这种方式很有用。但这种方式稍微复杂一些。

    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
