Hi,

in my program I want to "specify" that some object implements i.e. the
dictionary or list interface.
What is the Python way to do that?

i.e. in Java I'd include an interface.
in Python I could write an abstract class and inherit from it (probably
needs multiple inheritance), or I could just specify that in a comment.

What'd you suggest?
Thanks in advance
Uwe

I usually do that this way:

class IExpense:
def id(self):
raise NotImplementedError

class TimeExposure(IExpense):
def __init__(self, ...):
...

def id(self):
...
