Can someone explain to me what the following are and how it is supposed to be used:
1. Global Constant
2. Precedence of Operators
3. __builtin__
4. main
5. raw_input
Also, how come whenever I type in
>>>def f():
return 2, 34.7, "hi"
I get this instead:
>>>f()
(2, 34.7000000003, 'hi')
Notice how the number has changed.
