Ubuntu – Which Linux library should I use to call a method by pressing a key?

i am trying to call a specific method by pressing a key for example: something like this:
`

import keyboard

list = ["a","b","c"]

while True:
    try:
        if key.is_pressed('i'):
            list.index("a")
        elif key.is_pressed('c'):
            list.count("a")
    except:
        print("Error!")

I tried msvcrt library and found out it was only available for windows(I am using linux ubuntu 22.04) I also tried this link and it did not work.

    You can try the readchar library. It has some limitations but works for a lot of simple use cases.

    You could use the well-known curses library. Short example:

    import curses

stdscr = curses.initscr()   # initialize curses

curses.halfdelay(1)         # wait 1 tenth of a second for keypress
t = 0
for ch in iter(stdscr.getch, ord('q')):
    if ch != curses.ERR:    # keypress
        print("You pressed %s in period %d"%(chr(ch), t))
    t += 1

curses.endwin()             # restore terminal
