The buttons of Circuit Playground Express include a slide switch (D7) and two tactile buttons (D4, D5).

Let's first look at the slide switch (D7):

The related encapsulation of the slide switch is also in cp, and the corresponding identifier is switch. We realize the state of the red LED through the state of this slide switch:

from adafruit_circuitplayground import cp
while True:
	cp.red_led = cp.switch

The other buttons are two light touch buttons (D4, D5):

Circuit Playground Express has two buttons. Button A is on the left and Button B is on the right. This has something to do with the internal markings. These buttons can be used as inputs.

from adafruit_circuitplayground import cp
while True:
	if cp.button_b:
		cp.red_led = True
	else:
		cp.red_led = False
