Question: I am desperately trying to find a way to get this working. I have a menu that use images for links. But in IE and FF there is an annoying border around the image that I don't know how to get rid of.

Would you be able to quickly tell me the CSS attribute to avoid this effect.

Thanks in advance for your time.

Antonio

Answer: 
Python's `==` operator is the same as `.equals()` in Java. You can override this with `.__cmp__()` in Python and `.equals()` in Java.

Python's `is` operator is the same as `==` in Java, and neither of these can be overridden.
The operator `==` compares object *references* for equality. The `equals` method is intended to perform *value* comparison -- for example, two distinct `String` objects that represent the same sequence of characters will compare equal if you use `equals`, but not if you use `==`.

As far as I know, operator overloading was left out of Java as a matter of language design. (Why the language designers built in an overload for `+` over `String` boggles my mind. Convenient, yes, but IMO that's cheating.)
