The answer may be a little out of scope because you are asking in a Python mailing list, but
if the interest is learning OOP concepts (and not OOP in Python), IMHO Java is better.

- Java forces everything to be implemented in OO model (classes)

- Java widely uses interfaces and abstract classes. Python has not the concept of interface, as it 
favors EAFP
and duck typing instead of creating base classes which establish contracts. Python also allows 
multiple inheritance,
which is *usually* a bad idea, unless the base classes are interfaces.

- In Java, interface/implementation separation is *usually* a bigger concern (eg getters and setters
are common in Java code, rare in Python code) .

I know that Python developers see Python as more pragmatic, more flexible and quicker/easier/less
bureaucratic to develop than Java, so my opinion may be controversial.
