hexKeyCode is the virtual keyboard mapping as defined by the Windows API. The list of codes is available on MSDN: Virtual-Key Codes (Windows)

First of all, you forgot to close the strings on lines 4 and 6.

But your main issue is that you call keyboard.read_key() once for each arm of your if statement. This makes your code wait for a keypress, check if it's 'enter', then wait for another keypress, check if it's 'q', and so on.

What you should do is save the key to a variable, then check the variable. It should look something like this:

import keyboard
while True:
    key = keyboard.read_key()
    if key == 'enter':
        print('Enter is pressed')
    if key == 'q':
        print('Quitting the program')
        break
    if key == 's':
        print('Skiping the things')
