Question

Here’s the faulty bit of my code:

class Room(object):
    def __init__(self):
        self.hotspots = []
        self.image = []
        self.item = []

    def newhotspot(*args):
        new = {'Name' : None,
               'id' : None,
               'rect' : None,
               'Takeable' : None,
               'Lookable' : None,
               'Speakable' : None,
               'Itemable' : None,
               'Goable' : None}

        for i in args:
            new[i[0]] = i[1]
        new['id'] = len(self.hotspots)
        self.hotspots.append(new)

CityTrader = Room()

CityTrader.newhotspot(('Name', 'Trader'),
                      ('Takeable', 'Yes'))

The goal is to have a dictionary with all the keys set to none but the ones specified.
However, when I run it I get:

[...]line 85 in <module>
('Takeable', 'Yes'))
[...]line 44, in newhotspot
new[i[0]] = i[1]
TypeError : 'Room' object does not support indexing

Anyone knows why and how to solve this?
It seems to work when it’s not wrapped inside a class.

You forgot the self parameter to newhotspot():

def newhotspot(self, *args):
    ...

Since self will be implicitly passed anyway, it ends up as the first item of args.
