04. Prerequisites & Requirements

Prerequisites and Requirements

If you can understand this code (maybe with the help of the random module documentation), you know enough Python for this course:

import random

def ChooseTwice(items):
    a = random.choice(items)
    b = random.choice(items)
    return a, b

names = ["Alice", "Bob", "Charlie", "Debra"]
(one, two) = ChooseTwice(names)
if one == two:
    print "%s is happy!" % one
else:
    print "%s likes %s!" % (one, two)

You can use a command-line interface (terminal). Some of the exercises in this course involve using a Unix-style command-line interface to enter commands, run Python programs, and navigate directories.

If you have taken our course on Git and Github, the level of command-line use in this course is similar.

You don't need to be a Web programmer. This course does include a small Web application and some HTML and JavaScript in examples, but you will not need to make changes in these languages.

You don't need any previous database experience. This course is an entry-level introduction to relational databases.

You need a programming text editor (such as Atom) installed on your computer. You should be able to use it to open and edit files of Python code.
