Hi. I'm just starting to use python.
I am anxious about how best to set and access items one level down in a
data structure if I am using __setitem__ and __getitem__.
At the moment I can do
for a data structure Data:
object.Data = { 'one' : [1, 2, {}, 4],
'two' : [5, 6, {}, 8]}
I can use normal __setitem__ and __getitem__ to address Data keys very
easily
However, if I wish to access object.Data['one'][0] for instance, I am
using the following:
object['three'] = [0, 'val0'] # set
x = object['three'][0] # get
Is this advisable? I'm worried the syntax is very odd.
Extract from an example class:
def __setitem__ (self,key,value):
if type(value) == list and type(value[0]) == int:
if key not in self.data:
self.data[key] = {}
self.data[key][value[0]] = value[1]
else:
self.data[key] = value
def __getitem__ (self,key,value=None):
if not value==None:
return self.data[key][value]
else:
return self.data[key]
