How to Code custom HotKeys in Python! смотреть онлайн

This video shows you how to code custom Hotkeys using Pynput and how to open up child programs using Popen.

If you have trouble installing Pynput:

Ascii character codes for vk (use the decimal column):

The main program (change the file name in function 1 to the file name of your file and make sure it is in the same directory):



from pynput.keyboard import Key, KeyCode, Listener
import subprocess as sp

extProc = None


def function_1():
global extProc
extProc = sp.Popen(['python', 'Your_File_Name_Here.py'])


def function_2():
global extProc
if extProc is None:
print("You Haven't started silly, there is nothing to stop")
else:
sp.Popen.terminate(extProc)


combination_to_function = {
frozenset([Key.ctrl_l, Key.alt_l, KeyCode(vk=75)]): function_1,
frozenset([Key.ctrl_l, Key.alt_l, KeyCode(vk=80)]): function_2,
}

pressed_vks = set()


def get_vk(key):
return key.vk if hasattr(key, 'vk') else key.value.vk


def is_combination_pressed(cobination):
return all([get_vk(Key) in pressed_vks for Key in cobination])


def on_press(key):
vk = get_vk(key)
pressed_vks.add(vk)

for combination in combination_to_function:
if is_combination_pressed(combination):
combination_to_function[combination]()


def on_release(key):
vk = get_vk(key)
pressed_vks.remove(vk)


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



Child program (make sure it is in the same directory):



import time

time.sleep(3)

print('hello world')
