Does python support operator overloading?
what is the difference between __new__ and __init__?
does python support method overloading?

1) Learn to read the references documents (http://docs.python.org/ref/specialnames.html)
2) See here (http://www.python.org/download/releases/2.2.3/descrintro/#__new__)
3) There is no method overloading in Python, AFAIK

Best site,IMO, to learn about Python here (http://www.python.org/doc/).
