Like people, computers have their own language they use to communicate. Computers use a written language called source code to work, and humans can tell computers to do things by writing source code. Source code is a language that contains numbers, symbols, and words. In Code Combat players are able to explore, learn, and practice three different script languages including the popular Python and JavaScript, and an experimental code called CoffeeScript.

What is Python Script....
What is Python Script....
Python is one of the easiest script languages to use because it looks a lot like the text in books. Python uses commands that are easy to read and leaves spaces for comments about the code for the code writers. Python has many different commands including methods, arguments, strings, variables, and loops. Each command tells the computer to do something. In this Liftoff Challenge, you will program commands to help your hero avoid traps and defeat evil.

Methods
Methods
Methods are actions your hero can do with their gear. Your hero has feet so he can move up, down, right, or left. At the end of each method there are parenthesis where an argument can go, shown in the example below.
Arguments and Strings
Arguments and Strings
Arguments in Python tell the computer details about a method or action. For example, you could tell the computer to move the hero right with hero.moveRight(), or you could use an argument to be more specific about how far you want your hero to move right. You could tell the computer to move the hero one space, two spaces, or even farther.
A string is a special piece of text information. To tell the computer about a string, surround text with quotation marks.
You can combine arguments and strings. If you write hero.moveRight(4), your hero will move to the right 4 spaces. In another example, you could tell the computer to have the hero attack with hero.attack(), if you want your hero to attack the enemy Treg, your command would be hero.attack("Treg").
Variables
Variables
Variables are symbols that represent data, but unlike arguments, variables can change. When you are fighting ogres such as Treg, it takes a long time to type in their names one by one. Imagine if you had to fight a whole army of ogres! Instead of typing their names one by one like hero.attack("Treg"), you can use variables to attack the closest ogre and then attack the next closest ogre with hero.findNearestEnemy().
Loops
Loops
Sometimes a certain piece of code needs to be repeated over and over. Maybe you need your hero to dodge a fireball or you need them to travel in a circle around and around. You can use a "while-true" loop and tell the computer to repeat an action however many times you want. In the example below, the hero needs to move through a maze with the same moves over and over. Instead of writing out each step, I can write out the series and tell the computer to repeat or loop any number of times.
