Tutorials
Learn python in short, easy to follow tutorials.
Numbers in Python work like numbers you've seen elsewhere.
Let's now turn to how it handles inequalities — things that are either true or false.
Computer scientists have a special word for text: "strings".
Learn other ways to change strings.
Variables in computer science are pretty different than those in math, even though they're called the same thing.
If statements are how you direct Python to do something if something else is true.
Python offers a tool called lists to keep track of related "things," or values.
While loops tell the computer to do something while something else is true.
Dictionaries are another tool, built-in to Python, to store things. Things in dictionaries can be alike, too, though dictionaries are best used to translate keys to values.
Sometimes when programming it's helpful to use random numbers.
