The task: may I use it?

Write allowed(licence, use) that returns True or False for a proposed use, given LICENCES where each entry is (may change, may sell, must share changes). A use of "change" needs may change; "sell" needs may sell; "use as is" is always allowed. For each (licence, use) in requests, print <licence> / <use>: yes or : no. If the licence is not in LICENCES, print <licence> / <use>: unknown licence. At the end print allowed: <n> of <total>.

# the two lines every program starts with: the commands, then the robot
from bugbot import *
connect()

# licence: (may change, may sell, must share changes)
LICENCES = {"MIT": (True, True, False), "GPL": (True, True, True), "All rights reserved": (False, False, False)}
requests = [
    ("MIT", "change"),
    ("MIT", "sell"),
    ("GPL", "change"),
    ("All rights reserved", "change"),
    ("All rights reserved", "use as is"),
    ("CC BY", "sell"),
]
