void setup() { Serial.begin(9600); for(int pin = 2; pin <= 6; pin++) { pinMode(pin, INPUT); } } void loop() { String status = ""; byte checksum = 0; for(int pin = 2; pin <= 6; pin++) { byte state = digitalRead(pin); status += String(state); checksum += state; if(pin < 6) status += ","; } // Send with checksum for validation Serial.println(status + "#" + String(checksum)); delay(50); // Faster sampling rate }

Here's the equivalent Python code for the given Arduino sketch:

```python
import RPi.GPIO as GPIO
import time

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Define the pins to read from
pins = [2, 3, 4, 5, 6]

# Initialize the GPIO pins as inputs
for pin in pins:
    GPIO.setup(pin, GPIO.IN)

try:
    while True:
        # Initialize the status string and checksum
        status = ""
        checksum = 0
        
        # Read the state of each pin and calculate the checksum
        for pin in pins:
            state = GPIO.input(pin)
            status += str(state)
            checksum += state
            if pin < 6:
                status += ","
        
        # Send the status with checksum for validation
        print(status + "#" + str(checksum))
        
        # Wait for 50 milliseconds before the next reading
        time.sleep(0.05)
except KeyboardInterrupt:
    # Clean up GPIO when the program is interrupted
    GPIO.cleanup()
```

This Python code uses the RPi.GPIO library to interact with the GPIO pins on a Raspberry Pi. The code sets up the GPIO pins as inputs, reads the state of each pin, calculates the checksum, and sends the status with checksum for validation. The code also includes a try-except block to handle keyboard interrupts and clean up the GPIO pins when the program is interrupted.

Note: This code assumes that you are using a Raspberry Pi and the RPi.GPIO library. If you are using a different platform, you may need to use a different library or approach.
