[help requirement] pynput does not send ctrl+c to copy selected text

[retsyo]

I am using python 2.7 on win7 64 bits. Here is a code, which just replaces every selected text by <h1>text</h1>. pynput-1.6.8 is used for global hotkey and keypress, while pyperclip-1.7.0 is used to handle clipboard.

But I found that in fact, ctrl+c is not pressed at all.

What is the problem? Thanks

from pynput.keyboard import Key, Controller, GlobalHotKeys
import pyperclip

# initilize the clipboard to null
pyperclip.copy('')

keyboard = Controller()

def on_activate_h():
    print('<ctrl>+<alt>+h pressed')

    # copy current text to clipboard
    # but in fact, it does not work on my PC
    # why??
    keyboard.press(Key.ctrl)
    keyboard.press('c')
    keyboard.release('c')
    keyboard.release(Key.ctrl)

    txt = pyperclip.paste()
    if txt:
        keyboard.type(f'<h1>{txt}</h1>')

def on_activate_i():
    print('<ctrl>+<alt>+i pressed')

with GlobalHotKeys({
        '<ctrl>+<alt>+h': on_activate_h,
        '<ctrl>+<alt>+i': on_activate_i}) as h:
    h.join()

When on_activate_h evaluate, <alt> not released, so system actual got <ctrl>+<alt>+c.

solution:

def on_activate_h():
    # ...........
    keyboard.release(Key.alt)
    with keyboard.pressed(Key.ctrl):
        keyboard.press('c')
        keyboard.release('c')
   # ................
