Standard behaviour of a getSomething method

B

Batista, Facundo

When I want to know about a attribute (e.g.: myAttrib) of an object, I
should use the specific method (e.g.: getMyAttrib).

Considering that this attribute is always another object (everything is an
object in Python), what should getMyAttrib do?

1) Return the object
2) Return a copy of the object

How do I return a copy of the object?

Thanks for all.

I do not think there is a definite rule regarding this. However,
whichever one it does, you should probably document it :eek:)


How do I return a copy of the object?

You can use the copy module to create either a shallow or deep copy.

When I want to know about a attribute (e.g.: myAttrib) of an object, I
should use the specific method (e.g.: getMyAttrib).
Its not really considered "pythonic" to access attributes through
getters and setters. Instead, you can access them directly:
.... def __init__(self, val):
.... self.a = val
....
If you need to to other processing of the data for the data (ie, if you
wanted to give a copy), you can use the __getattr__ and __setattr__
methods.
Considering that this attribute is always another object (everything is
an object in Python), what should getMyAttrib do?

1) Return the object
2) Return a copy of the object

How do I return a copy of the object? try looking at:
