How to check if class instance exists in a list of class instance objects?

[sonicblind]

Hi,

I have a list of class instances:

mylist = [ myClass(name=n1), myClass(name=n2), myClass(name=n1), myClass(name=n3) ]

How can I get rid of duplicates in this list?
I know that the two instances with the name='n1' are in reality 2 different objects, so they are in reality not duplicates.
But for my project, having several instances with the same parameters means basically duplicates and I need to clean up the list accordingly.

Is there any easy way to do it?

Thanks.
