1: Get Ready For The Python Difference
*********************************************
Summary
-----------
- Objects do carry an indication of type, but variables are untyped
- Integers in python have an unlimited number od digits
- Variables store references to objects, not values
- Strings are immutable and support slicing
- The list does the work of an array in other languages
- The dictionary is essentially an associative array
- The tuple is a lightweight immutable list
- Code indentation alters the meaning and matters
- Classes are objects
- Objects have attributes, some of which can be functions
- Inheritance works much like other languages, but class objects are directly involved in retrieving attributes
- Modules are how Python Code is packed into larger units

Objects
----------

Everything is an object

- The program (module)
- variables (names are just pointers)
- functions
- classes

Basic Python
---------------

.. code-block:: python

    s = "Strings" # no declaration like "int" or "str"
    x = 5

    #Math
    sum = 5 + 4
    sub = 5 - 4
    product = 5 * 4
    quotient = 5 / 4
    remainder = 5 % 4
    count = count += 1

    #functions
    
    def add(x,y):  # def is a python command that tells the program to look at the object that "add" points to
    # notice the ":" when a colon is used everything underneath is a part of that line, this is used in loops, functions, and conditionals
        return x + y
    print(add(2,3)) # prints 5

    # can be done with strings as well ex add("lumber", "jack") prints "lumberjack"


Objects in Code
--------------------

.. code-block:: python

    class point:
        def __init__(self): # the initializer
            self.position=(0,0)
        def setpos(self,x,y): #setter
            self.position=(x,y)
        def display(self): #getter
            print(self.position)

Modules
-----------

Python scripts can be an object themselves. Scripts can be imported as modules to other python programs which can access the original scripts objects, or only specific objects 

.. code-block:: python

    import modulename
