Answer 1

You need to pass a function to keyboard.on_press

Try:

def pressed(key):
    if key.name == 'esc':
        # Do something here

keyboard.on_press(pressed)

while True:
    # Do something else while you wait

Answer 2

it works now thanks

start = 1

def pressed(key):
    global start
    if key.name == 'esc':
        if start == 0 :
            start = 1
        elif start == 1:
            start = 0

keyboard.on_press(pressed)

while start == 1:
    print('yes')
    time.sleep(1)
