conditional statement

A statement that controls the flow of execution depending on some condition.

condition

compound statement

A statement that consists of a header and a body. The header ends with a colon (:). The body is indented relative to the header.

block

A group of consecutive statements with the same indentation.

body

The block in a compound statement that follows the header.

nesting

One program structure within another, such as a conditional statement inside a branch of another conditional statement.

recursion

The process of calling the function that is currently executing.

base case

A branch of the conditional statement in a recursive function that does not result in a recursive call.

infinite recursion

A function that calls itself recursively without ever reaching the base case. Eventually, an infinite recursion causes a runtime error.
