generate_uuid.py

#!/usr/bin/python3

"""
Use this script to generate random strings

USAGE:
    -q sets the amount of IDs to generate, default 1
    -l sets the length of each ID, default 8


FOR LINUX USERS:
    I personally run this command: ./generate_uuid.py | xclip -selection c -rmlastnl
    This will automatically copy the output to my clipboard
    Note that just selecting the output and copying and pasting manually is sufficient
