lets make an stack...
lets make a class
TIP: The initial step to make a class is defining its API (what is API?)
| function/variable | arguments | returns | description |
|---|---|---|---|
| push | value:[anytype] | None |
pushes value into stack |
| pop | - | last item in the stack, None if stack is empty |
removes the last item in the stack and returns it |
| lastItem | - | last item in the stack | like pop but without removing |
| isEmpty | - | True or False |
returns True if stack is empty |
| size | - | int |
returns the number of items stored in the stack |
| str | - | ? | ? |
| eq | other stack | ? | ? |
Question

How to force user not to have access to main data in class?
Question
define terms public, private and protected.
class test:
"""docstring for test."""
def __init__(self):
self.public='public' # this is public
self._protected="protected" # this is protected
self.__private="private" # this is privateNOTE: that was all joke!!! :)
