Example Python Script: capture_images_by_key.py Elevated Privileges

[baqwas]

While running the script capture_images_by_key.py from the examples folder, I encountered the following error:

In main
    if is_pressed('p'):
  File "/home/user/.local/lib/python3.9/site-packages/keyboard/__init__.py", line 410, in is_pressed
    _listener.start_if_necessary()
  File "/home/user/.local/lib/python3.9/site-packages/keyboard/_generic.py", line 35, in start_if_necessary
    self.init()

    raise ImportError('You must be root to use this library on linux.')
ImportError: You must be root to use this library on linux.

I understand that the Picamera2 team cannot do much about the privileges for running the keyboard package (that was installed via pip without elevated privileges), is there an alternative package for evaluation purposes. After all, we routinely use similar examples in OpenCV without elevated privileges (cv2.waitKey(wait_period) since it is baked into OpenCV). What would be an alternate package for consideration by a newbie user without needing elevated privileges? Thanks.

Regards.

P.S.
The user identified as user in the above section has admin rights on the computer.

Example 1:

import pynput.keyboard as keyboard

def on_press(key):
    print('The key {} was pressed.'.format(key))

Example 2:

import msvcrt

if msvcrt.kbhit():
    key = msvcrt.getch()
    print('The key {} was pressed.'.format(key))
