2. Simply Button import RPi.GPIO as GPIO import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.IN,pull_up_down=GPIO.PUD_UP)
while True:
input_state = GPIO.input(17)
if input_state == False:
print('Thanks MESEF')
time.sleep(0.2)

3. 2 Buttons from time import sleep import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
button1=17
button2=12
GPIO.setup(button1,GPIO.IN,pull_up_down=GPIO.PUD_UP)

while(1):
if GPIO.input(button1)==0:
print("Button 1 was pressed:")
sleep(0.1)
if GPIO.input(button2)==0:
print("Button 2 was pressed:")

4. Simple LED from gpiozero import LED from time import sleep
led = LED(17)
while True:
led.on()
sleep(2)
led.off()

5. Button and LED from time import sleep import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
button1=17
LED1=21
GPIO.setup(button1,GPIO.IN,pull_up_down=GPIO.PUD_UP)
GPIO.setup(LED1,GPIO.OUT)
BS1=False
while(1):
if GPIO.input(button1)==0:
print ("Button 1 was pressed")
if BS1==False:
GPIO.output(LED1,True)
BS1=True
sleep(0.5)
else:
GPIO.output(LED1,False)
