Python comes in a variety of data types. Before we go over the more interesting data structures (like collections) let's take a brief tour of the primitive data types - booleans, numbers and strings. We'll start with the most basic type - Booleans.
Booleans contain just two values -
False. These values are case-sensitive, so don't forget to uppercase the first letters!
Booleans can be the result of expressions.
>>> 2 < 3 True >>> 2 > 3 False >>> 2 < 2 < 1 False
False are interchangable with 1 and 0. Additionally, the empty string "" is treated as
False, while all other values are equivalent to
True. It's best practice to use actual boolean types.
Booleans have operators
or that can be used in conjunction with boolean data types.
>>> not True False >>> True and False False >>> False or True True
Later on you'll see that booleans are used in conditional statements for flow control. For example, in an if statement, the block of code that becomes execute depends on the boolean value of the expression proceeds the if statement.
