Python: Getting Started

April 3 2014

Hosts: Fr. Robert Ballecer, SJ and Shannon Morse

Guest: Dale Chase

This week we are introducing our newest module, Python with Code Warrior Dale Chase!

How to Install Python

Go to Python.org and click on Python 2.7.6 under "Download". Choose the installer package for your operating system and click on them. The file will be downloaded. It is important to download 2.7 because 3.4.0 is NOT compatible with our lessons. If you want more information on what the differences are between 3.x and 2.x, please check out this handy information.
** Note: Python is AUTOMATICALLY INCLUDED ON Mac OS X ... however, you should probably download the latest rev2 version. **

Viewer submissions and questions will be back next week!

To see all the code used in today's episode, go to Our Github Repository for Module 2

Ivory Tower

Compiled vs. Interpreted Languages
* Compiled languages are reduced to a set of machine-specific instructions before being saved as a executable file
* Intepreted Languages are saved in the same format that you entered, then converted into machine language "Just in Time" - when they are needed.
-- Compiled Languages generally run faster, but are a little trickier to develop since they much be compiled for each platform that may use the program
-- Interpreted Languages generally run more slowly than Interpreted languages, but are more convienent for developers.

Whitespace
* In C#, you ended a line of code by typing ";"
* In Python, the WHITESPACE deliniated lines of code

Dynamic Variables
* In C#, we had to explicity declare variables to reserve memory space.

INT (Integer) = 2 Bytes 65536
LONG INT (Integer) = 4 Bytes 4,294,967,296
CHAR (Character) = 1 Byte 256
FLOAT (Floating Point = 4 Bytes 4,294,967,296

* We had to tell C# EXACTLY what type of data would be going into the variable, and it would reserve the necessary space in memory.

** We don't have to do that in Python.
-- Variables in Python are declared AUTOMATICALLY when a value is stored in the variable.

Here's how it works.
"Var1 = 100
Var2 = ""Hello World""
Var3 = ""3.14""" "This becomes an INT
This becomes a STRING
This Becomes a FLOAT"

Python has several Data Types:
"* Numbers
* Strings
* Lists
* Tuple
* Dictionary" "* (int, long, float, complex)
* Contiguous Set of Characters
* Arrays
* Read-Only Lists
* A Hash Table
"

Output to Screen
print "Hello World"
- or -
"Yo = ""Hellow World""
print Yo"

Input from user:
* Python has a built-in function called "raw_input()"
* When you use this function as follows:
"var1 = raw_input(""What's your age?"")
print var1"
