Learn to code in 60 seconds. A program is a coded set of instructions for a computer to execute. Programs manipulate data, which come in several data types: integers, that's whole numbers; floats, have decimal points; booleans, true or false; and strings, of characters (don't forget the quotation marks).

Need to store a piece of data for later use? A variable names its location and points to it. Have a bunch of data? Organize it with a data structure. Lists store data in an ordered sequence, but we start counting at an index of zero. Dictionaries associate each piece of data with a key for easy lookup.

To make decisions in a program, ask a question with a Boolean expression. Then, choose which path to take with an if statement. To repeat a code routine, use a loop. A while loop repeats until the answer to your question becomes false. A for loop repeats a fixed number of times.

Have a lot of code? Break it down into smaller tasks with functions. Customize the function with input arguments and call the function to execute its task. Did you catch all that? Take it at your own pace with Khan Academy's intro to computer science course.
