    If statement behaving oddly

    Hello,

    I've come across an unexpected issue that may be hard to diagnose due to required hardware, but here goes.

    I have a Raspberry Pi connected to an LCD display that I'm testing turning the screen on and off (not worrying about displaying text, I've previously written a program that uses a DHT22 sensor to display the temperature & humidity and external weather conditions using the Pirate Weather API).

    While trying to write a simple program just to turn the display on or off, I run into an issue.

    Here's the code: 

     undefined
        
import board
import datetime
# I2C driver from:
# https://gist.github.com/vay3t/8b0577acfdb27a78101ed16dd78ecba1
import I2C_LCD_driver
import argparse
parser = argparse.ArgumentParser()
parser.add_argument("state", help="'on' to turn on the screen, 'off' to turn off",type=str)
args = parser.parse_args()

mylcd = I2C_LCD_driver.lcd()

match args.state:
    case "on":
        power = 1
    case "off":
        power = 0
    case _:
        print("Please enter 'on' or '

    Hello and welcome

    Hello!

    I noticed that there was a standard python community on lemmy, but no community geared toward learning the language specifically.

    Given the lower user count on lemmy, it will probably take some time for this community to grow, but I am hopeful it can become useful at some point.

    If you are coming from reddit, the rules are the same as the subreddit for the same topic.

    Thanks!
