Simulate keystroke in Linux with Python
提问by microo8
How can I simulate a keystroke in python? I also want to press multiple keys simultaneously.
如何在python中模拟击键？我也想同时按下多个键。
Something like:
就像是：
keystroke('CTRL+F4')
or
或者
keystroke('Shift+A')

Although it's specific to X, you can install the xautomation package (apt-get install xautomationon Debian-based systems) and use xteto simulate keypresses, e.g.:
尽管它特定于 X，但您可以安装 xautomation 包（apt-get install xautomation在基于 Debian 的系统上）并用于xte模拟按键，例如：
from subprocess import Popen, PIPE
control_f4_sequence = '''keydown Control_L
key F4
keyup Control_L
'''
shift_a_sequence = '''keydown Shift_L
key A
keyup Shift_L
'''
def keypress(sequence):
p = Popen(['xte'], stdin=PIPE)
p.communicate(input=sequence)
keypress(shift_a_sequence)
keypress(control_f4_sequence)

Pythonic API to Linux uinput kernel module...
Python-uinput is Python interface to Linux uinput kernel module which allows attaching userspace device drivers into kernel. In practice, Python-uinput makes it dead simple to create virtual joysticks, keyboards and mice for generating arbitrary input events programmatically...

If you are on Windows, use Sendkeysand if on Linux, try out the suggestion given herefor xsendkeys or pexpect.
如果您使用的是 Windows，请使用Sendkeys；如果使用的是 Linux，请尝试此处针对 xsendkeys 或 pexpect给出的建议。

Consider python-uinputand evdev. Example of shift+awith the latter:
考虑python-uinput和evdev。shift+a后者的例子：
from evdev import uinput, ecodes as e
with uinput.UInput() as ui:
ui.write(e.EV_KEY, e.KEY_LEFTSHIFT, 1)
ui.write(e.EV_KEY, e.KEY_A, 1)
ui.syn()

If you plan to use it on Linux, try pyautoguilibrary. For multiple keys you will need to use hotkey, e.g.:
如果您打算在 Linux 上使用它，请尝试使用pyautogui库。对于多个键，您需要使用热键，例如：
pyautogui.hotkey('ctrl', 'c') # ctrl-c to copy
For me it worked - see here: How to pass a keystroke (ALT+TAB) using Popen.communicate (on Linux)?
对我来说它有效 - 请参阅此处： How to pass a keystroke (ALT+TAB) using Popen.communicate (on Linux)？
