Encoding and mac-vendor-lookup library

[tuanjggaa]

Hi everyone!
I'm pretty new to python, so i want to look-up a mac address using mac-vendor-lookup library.
When i run the script on my laptop (Intel-P 3.7.4) everything works fine, but when i run it with my PC (AMD-P 3.8.1)
It's got error:
Here's the error.

Output:
C:\Users\ADMIN>python

Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 22:39:24) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from mac_vendor_lookup import *
>>> a = '18:60:24:aa:dd:bd'
>>> print(MacLookup().lookup(a))

Error:

I Hope you guys can help me out.
