 Python 3.x
Code
```python
import time
import RPi.GPIO as GPIO
# Set up GPIO pins
GPIO.setmode(GPIO.BCM)
voltagePin = 17  # Voltage input pin
currentPin = 23  # Current input pin
while True:
    # Read voltage value
    voltageValue = GPIO.input(voltagePin)
    voltage = voltageValue  (100.0 / 1023.0)  # Convert digital value to voltage (0-100V)
# Read current value
    currentValue = GPIO.input(currentPin)
    current = currentValue  (100.0 / 1023.0)  # Convert digital value to current (0-100A)
print("Voltage: {:.2f}V".format(voltage))
    print("Current: {:.2f}A".format(current))
time.sleep(1)
