Ivory Tower

Structured Data in Python

* Data Structures are important because they allow us to not only store data, but to make correlations between sets of data.

* Correlated data is an important piece in being able to break down the world into a computer language

One of the most basic data structures in Python is the LIST

* A list is a sequence of variables connected to one another * The Syntax for a list is: "NameOfList = [value1, value2, value3, value4]; The name of your list = [values];" To access the values contained within the list, you use the syntax: " NameOfList[index] " Where "index" is a number between 0 and the number of values in your list-1 Example: c101 = ['PadreSJ', 'Snubs', 'Dale Chase', 'Cranky_Hippo']; Will create a list named "c101" with entries 0-3 with the values of "PadreSJ", "Snubs", "Dale Chase", and "Cranky_Hippo" If we wanted to access that list, we could write: print ""The Following are members of the Coding 101 team:", c101[0], c101[1], c101[2], c101[3]" I could also update the values in the list by using the name of the list and the index I want to change: Example: c101[3] = "Bryan Burnett" Will change the value of the 4th element from "Cranky Hippo" to "Bryan Burnett"
