python - 无法在 pynput 中选择文本

Question

我正在使用 pynput 库编写一个 python 脚本，我想在其中选择特定长度的文本。

为此，我首先按 Shift 键，然后按多次向左箭头键。这样光标 id 左边的文本就被选中并可以进一步用于复制目的。

这是我的代码:

from pynput import keyboard
from pynput.keyboard import Controller

keyboard_controller = Controller()
with keyboard_controller.pressed(keyboard.Key.shift_l):
    keyboard_controller.press(keyboard.Key.left)
    keyboard_controller.release(keyboard.Key.left)
    keyboard_controller.press(keyboard.Key.left)
    keyboard_controller.release(keyboard.Key.left)
    keyboard_controller.press(keyboard.Key.left)
    keyboard_controller.release(keyboard.Key.left)

这会将光标向左移动 3 步，但即使按下 Shift 键，文本也不会被选中。我在这里缺少什么？

OS: Windows 10

Environment: Python 3.6.5

这是我的 vs 代码中发生的情况的演示。

Answer 1

也许试试这个？

from pynput.keyboard import Key
from pynput.keyboard import Controller

keyboard = Controller()

选项 1:

with keyboard.pressed(Key.shift):
    keyboard.press(Key.left)
    keyboard.release(Key.left)
    keyboard.press(Key.left)
    keyboard.release(Key.left)

选项 2:

keyboard.press(Key.shift)
keyboard.press(Key.left)
keyboard.release(Key.left)
keyboard.press(Key.left)
keyboard.release(Key.left)
keyboard.release(Key.shift)

选项 3:

keyboard.press(Key.shift.value)
keyboard.press(Key.left.value)
keyboard.release(Key.left.value)
keyboard.press(Key.left.value)
keyboard.release(Key.left.value)
keyboard.release(Key.shift.value)

这是它在我的机器上运行的视频证明:)
