Overloading __getitem__

[Andreas Matthias]

The following code doesn't run but I hope you get what I
am trying to do.


class my_dict (dict):

def __getitem__ (self, key, crazy = False):
if crazy == True:
return 5 * self.get(key)
else:
return self.get(key)


foo = my_dict()
foo['a'] = 123

print foo['a']
print foo['a', crazy = True]


Is it somehow possible to overload __getitem__ with an additional
argument? Are there other possibilities to achiev this? Or is
the only solution to this to write a normal function call
`def my_get (self, key, crazy=False)'?


Ciao

Oh, I didn't know that. I totally misinterpreted the error message.

Apparently, args already is a tuple, so this should be:

  def __getitem__(self, args):

Is this documented somewhere? I couldn't find it anywhere.

Thanks.
