Python Chapter 3/part 3

Fuctions: A block of organised, reusable code that is used to perform a single realted action. remeber to import fuctions from python

e.g:def addition(a,b): total = a + b return total

another way of calling input e.gnum1 = int(input("Enter car 1"))

default fuctions: fuctions that are set by default. We use this because we don't want the user to enter anything sometimes or user forgets to enter prementer value.e.g.def CreateAnArcade(name, games, helipad = "NO", high_def = "YES"): print("name:",name) print("games:"games) print("helipad:"helipad) print("high def:",high def) return;return;= return the body of fuction
