function

A ___ is a group of statements that exists within a program for the purpose of performing a specific task

divide and conquer

A large task is divided into several smaller tasks that are easier to perform. This technique is known as ___

true

T/F: If a specific operation is performed in several places in a program, a function can be written once to perform that operation, and then be reused any time it is needed

void function

When you call a ___, it simply executes the statements it contains and then terminates

value-returning function

When you call a ___, it executes the statements that it contains, then returns a value back to the statement that called it

code reuse

Writing the code once to perform a task, and then reusing that code each time you need to perform the task

a function header and a block

function header

T/F: When the end of a function is reached, the computer returns control back to the beginning of the program.

true

T/F: The Python interpreter uses indentation to determine where a block begins and ends.

top-down design

a design process in which an algorithm is broken into functions

hierarchy charts

a chart that shows the relationships between functions

true

T/F: In top-down design, tasks are broken down into subtasks until no more subtasks can be identified.
