dictionary mutability, hashability, __eq__, __hash__

I was reading this: http://stackoverflow.com/questions/4418741/im-able-to-use-a-mutable-object-as-a-dictionary-key-in-python-is-this-not-disa In a User Defined Type, one can provide __hash__ that returns a integer as a key to a dictionary. so: d = { key : value } What is the significance of

What exactly is a python variable?

In C: int x = 10; results in storage being allocated and type and location are fixed for the life of the program. In Python, x = 10 causes an object '10' to be created but how exactly is 'x' handled? Symbol Table lookup at compile time? Is every 'x' being substituted out of existence?

__debug__ http://stackoverflow.com/questions/15305688/conditional-debug-statement-not-executed-though-debug-is-true

Trying to make sense of that article. My understanding of debug was simple: 1. __debug__ is always True, unless -O or -OO 2. 'if' is optimized out when True and the expr is inlined. So what does he mean by: 1. 'If you rebind __debug__, it can cause symptoms' 2. 'During module compilation, the

What is the difference between class Foo(): and class Date(object):

>>> class Foo(): ... pass ... >>> class Bar(Foo): ... pass ... >>> b = Bar() >>> type(b) >>> class Date(object): ... pass ... >>> class EuroDate(Date): ... pass ... >>> x = EuroDate() >>> type(x) What is going on here? Shouldn't x = EuroDate(); type(x) give 'instance'?? Why is 'b'
