python code to wait for push button to be pushed

I am using python to control an arduino.I want the python code to wait for the button to be pressed, and then move onto the next line.In the current code I have, the code sleeps for x seconds and checks if button has been pushed,if button is not pushed, it skips it. This is my current code:

    if bool(push_button2.read()):
        print('Please press any button when done')
        sleep(2)
        if bool(push_button1.read()) or bool(push_button2.read()):

The problem with this is if push_button1 or push_button2 is not pressed, it will move onto the next code.So is there a way to make python wait for an input via the push button? Thanks

You can use while for this:

while(!push_button2.read())
    pass

Or you can even add s small sleep() here:

while(!push_button2.read())
    sleep(0.01)

And finally, you can write your own functions:

# wait for one button
def wait_for_button(button):
    while(!button.read())
        pass

# wait for any button from a set
# usage: wait_for_any_button(button1, button2)
def wait_for_any_button(*args):
    while !any(map(lambda b: b.read(), args)):
        pass

# if you need a button index
def wait_for_any_button_i(*args):
    while True:
        for i, button in enumerate(args):
            if button.read():
                return i
