在Python中，可以使用pyautogui库来模拟鼠标和键盘输入，并添加延迟，下面是一个例子，说明如何使用pyautogui.typewrite（）函数来模拟在每个字符之间延迟2秒的消息输入：

import pyautogui
import time

# Type a message
message = "Hello World"

# Add delay of 2 seconds between each character
for char in message:
    pyautogui.typewrite(char)
    time.sleep(2)

类似地，可以使用pyautogui.moveTo（）函数模拟鼠标移动的延迟：

import pyautogui
import time

# Move mouse to (100, 100) with a delay of 2 seconds
pyautogui.moveTo(100, 100, duration=2)

# you could also use time.sleep(2)
time.sleep(2)
