详细的pynput库的所有用法

pynput是一个Python库，用于控制和监视输入设备，如鼠标和键盘。以下是pynput库的所有用法：

1. 控制键盘输入

from pynput.keyboard import Key, Controller

keyboard = Controller()

# Type a lower case 'a'
keyboard.press('a')
keyboard.release('a')

# Type two upper case 'A's
keyboard.press(Key.shift)
keyboard.press('a')
keyboard.release('a')
keyboard.release(Key.shift)

# Type 'Hello, World' using the shortcut type method
keyboard.type('Hello, World!')

2. 监视键盘输入

from pynput import keyboard

def on_press(key):
    try:
        print('Key {} pressed.'.format(key.char))
    except AttributeError:
        print('Key {} pressed.'.format(key))

def on_release(key):
    print('Key {} released.'.format(key))

with keyboard.Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()

3. 控制鼠标移动

from pynput.mouse import Controller

mouse = Controller()

# Move the mouse relative to its current position
mouse.move(5, -5)

# Set the mouse position
mouse.position = (10, 20)

4. 控制鼠标点击

from pynput.mouse import Button, Controller

mouse = Controller()

# Click the left button once
mouse.click(Button.left, 1)

# Double click the right button
mouse.click(Button.right, 2)

5. 监视鼠标输入

from pynput import mouse

def on_move(x, y):
    print('Pointer moved to {0}'.format((x, y)))

def on_click(x, y, button, pressed):
    if pressed:
        print('Mouse clicked at ({0}, {1}) with {2}'.format(x, y, button))

def on_scroll(x, y, dx, dy):
    print('Mouse scrolled at ({0}, {1})({2}, {3})'.format(x, y, dx, dy))

with mouse.Listener(on_move=on_move, on_click=on_click, on_scroll=on_scroll) as listener:
    listener.join()

6. 控制剪贴板

from pynput import clipboard

# Set the clipboard data
clipboard.copy('Hello, World!')

# Get the clipboard data
data = clipboard.paste()
print(data)

7. 控制屏幕截图

from pynput import mouse
from PIL import ImageGrab

# The captured image will be stored in this variable
image = None

def on_click(x, y, button, pressed):
    global image

    if pressed:
        # Capture the screen
        image = ImageGrab.grab()

with mouse.Listener(on_click=on_click) as listener:
    listener.join()

# Save the captured image to a file
image.save('screenshot.png')

这些是pynput库的所有用法，可以控制和监视输入设备，如键盘、鼠标和剪贴板，可以在需要的时候捕获屏幕截图。
