Hi Tutors, I'm confused by the following possible contradiction. Would someone please explain or point me to the right docs.
FACT 1 "Variables in python hold references to objects." http://en.wikipedia.org/wiki/Python_syntax_and_semantics FACT 2 >>>def Increment ( x ) : >>> // return x + 1 >>> x = x + 1 >>> return x >>> >>>y = 1 >>>z = Increment ( y ) >>>y 1 >>>z 2 By FACT 1 x should be a reference parameter...? By Fact 2 x would seem to be a copy...? What in the world of dynamic typing is going on? Many thanks, John
