So, im trying to make a script that takes code from a pastebin post and runs it. But, for some reason it doesnt run the code. I dont know why. Could someone explain why this wont work so i can fix the issue?

I tried:
(dont mind the imports im gonna use those for later)

```
import os 
from json import loads, dumps
from base64 import b64decode
from urllib.request import Request, urlopen
from subprocess import Popen, PIPE

def get_code():
  test = 'None'
  try:
    test = urlopen(Request('https://pastebin.com/raw/4dnZntN3')).read().decode()
  except:
    pass
  return test

test = get_code()

def main():
  test

main()

```

The output is empty, and no errors.
