How do I get my Python program to sleep for 50 milliseconds?

Question

如何让我的 Python 程序休眠 50 毫秒？

Answer 1

Use time.sleep()

from time import sleep
sleep(0.05)

Answer 2

Note that if you rely on sleep taking exactly 50 ms, you won't get that. It will just be about it.

Answer 3

Use time.sleep() :

import time
time.sleep(50 / 1000)

See the Python documentation: https://docs.python.org/library/time.html#time.sleep

Answer 4

There is a module called 'time' which can help you. I know two ways:

1. 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")

2. 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

Answer 5

You can also do it by using the Timer() function.

Code:

from threading import Timer

def hello():
  print("Hello")

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

Answer 6

You can also use pyautogui as:

import pyautogui
pyautogui._autoPause(0.05, False)

If the first argument is not None, then it will pause for first argument's seconds, in this example: 0.05 seconds

If the first argument is None, and the second argument is True, then it will sleep for the global pause setting which is set with:

pyautogui.PAUSE = int

If you are wondering about the reason, see the source code:

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)

Answer 7

import time as t
t.sleep(0.05) 

This should do the trick!
