Function Documentation

◆ VendTask()

def ME405_Lab0x01.VendTask ( denomDict )

Allows for the purchase of drinks with certain denominations.

Keyboard callbacks enable the user to select a desired drink and to pay for said drink from a fixed variety of denominations.

Parameters

denomDict Lists the possible denominations, from largest to smallest, that the user can pay with. Their values are integers specified in dollar amounts.

Returns: Returns the current state of the VendTask FSM

Variable Documentation

◆ denomDict

dictionary ME405_Lab0x01.denomDict

Initial value:

 =  {
             "Hamilton" : 10,
             "Lincoln" : 5,
             "Washington" : 1,
             "Quarter" : 0.25,
             "Dime" : 0.10,
             "Nickel" : 0.05,
             "Penny" : 0.01
                         }

◆ getDrink

def ME405_Lab0x01.getDrink = VendTask(denomDict)

Creates a generator object.

Creating a generator object will allow us to iterate through this theoretically infinite sequence per cycle of the FSM.
