How to Safe on GPIO Pin in raspberry pi

You want all the GPIO pins to be set to inputs whenever your program exits so that there is less of a chance of an accidental short on the GPIO header, which could damage your Raspberry Pi. Today I Show you How How Safe GPIO Pin in raspberry pi in easy Process you just use Use

try:
    your Code
finally:

construction and the GPIO.cleanup method.

Required Component connect LED Raspberry Pi :

1.Raspberry pi

2.Breadboard

3. Connecting wire

4.Resistors

5. 5mm LED

Connecting an LED to a Raspberry Pi4

Code Safe GPIO Pin in raspberry pi:

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)
try:
 while (True):
     GPIO.output(18, True)
     time.sleep(0.5)
     GPIO.output(18, False)
     time.sleep(0.5)
finally:
 print("Cleaning Up!")
 GPIO.cleanup()

when you start wiring up a new project, unaware of this problem, your new circuit might accidentally short a GPIO output to one of the supply rails or another GPIO pin in the opposite state. A typical scenario where this might happen would be if you were to connect a push switch, connecting a GPIO pin that you had configured as an output and HIGH to GND,
