5.8. Chapter Summary¶
This chapter included the following concepts from computing.
Abstraction - Abstractions in code are things that allow us to focus on the big picture - like
drawSquareinstead of the details required to actually do the job.
Argument - An actual parameter is a value passed into a procedure or function when it is called. In
forward(50)the actual parameter is 50. This is also called an actual parameter.
Call - You can call or run a procedure or function by using the name of the procedure or function followed by values to pass into the procedure or function. An example is
forward(50). This is also known as executing or running a procedure or function.
Define - You can define a new procedure or function in Python using the
Execute - Execute means to run or call a procedure or function.
Formal Parameter - A formal parameter is named input in the definition of a procedure or function. This is also called a parameter.
Function - A function is a named set of instructions that returns a result. An example is the
abs(num)which returns the absolute value of the num.
Library - A library is a named group of related procedures and functions. An example is the Turtle library.
Parameter - A parameter is input to a procedure or function that is named when you define the procedure or function. It will be assigned a value when you call the procedure or function. This is also called a formal parameter.
Procedure - A procedure is a named set of instructions that does not return a result, but can cause something to happen like the turtle
Run - To run a procedure or function use the name of the procedure or function in your program. This is also known as calling or executing a procedure or function.
