Python takes binary input and turns it into random numbers

Question

I am trying to make a mini 8-bit binary display using Pimoroni Blinkt! on Raspberry Pi, and when I input a binary number, it outputs random numbers: I enter 00010011 and it outputs 4105, when it should output 00010011

My code:

from datetime import datetime
import blinkt
import time

blinkt.set_clear_on_exit(False)
blinkt.set_brightness(0.1)

current_pos_bin = 0
#minute = '00010011'
binNum = input('Binary number: ')
listBin = list(str(binNum))
print(binNum)
print(listBin)

for i in listBin:
        if i == '0':
                blinkt.set_pixel(current_pos_bin, 0, 0, 0)
                blinkt.show()
        elif i == '1':
                blinkt.set_pixel(current_pos_bin, 255, 255, 255)
                blinkt.show()
        else:
                print('error')
        print(current_pos_bin)
        current_pos_bin += 1
        #time.sleep(1)
blinkt.show()

Are you using Python2 by any chance? Nvm, I had a second think about it and you're most likely not. — Torxed

Just put a proper shebang as the first line, i.e. #!/usr/bin/python3 and make the script executable with chmod +x YourScript.py then you can run it with ./YourScript.py — Mark Setchell

I am using python 3.8. I tried your code without using the blink library. It worked fine for me. Maybe take a closer look in the blink documentation or check your python version.

This still doesn't answer why the two print() outputs 4105 tho?

I've worked out it only works with python3, so I need to work out how to set that as default...
