How to pass an input variable to another def?

        def main():
           selectionvalid = False
           print("Welcome to virtue vending machine!")
           print("Machine only takes $1 bills")
           table()
           while True:
               user = input("Select your choice:")
               if user == 'A1':
                   selectionvalid = True
                   print("Snickers: $.89")
                   change = bills() - a1
               elif user == 'A2':
                   print("M&Ms: $1.39")
                   change = bills() - a2
                   selectionvalid = True
               elif user == 'A3':
                   print("M&Ms: $1.39")
                   change = bills() - a2
                   selectionvalid = True
               elif user == 'B1':
                   print("Lays: $.50")
                   change = bills() - a3
                   selectionvalid = True
               elif user == 'B2':
                   print("Doritos: $.50")
                   change = bills() - a3
                   selectionvalid = True
               elif user == 'B3':
                   print("Cheetos: $1.49")
                   change = bills() - a5
                   selectionvalid = True
               elif user == 'C1':
                   print("TicTac: $1.04")
                   change = bills() - a6
                   selectionvalid = True
               elif user == 'C2':
                   selectionvalid = True
                   print("Starburst: $.79")
                   change = bills() - a7
               elif user == 'C3':
                   selectionvalid = True
                   print("Skittles: $2.49")
                   change = bills() - a8
               else:
                   print("Item not available.")
                   print("Please, select your choice again:")
               if selectionvalid == True:
                   print("Your change is:$", format(change, '.2f'))
                   message()
                   break
               return selectionvalid

        def bills():
           totals = 0 
           bills = int(input("Insert your bills:$"))
           while bills > 4:
            print("Please, enter less than $4")
            bills = int(input("Insert your bills:$"))
           else:
            print("You've inserted $",bills,"dollars")
            return bills


        def message():
            print("Your,",,"is dispensed below!")
            print("Thank you! Come Again!")

I'm trying to get the user input selection to show up to def message() Is there another way to condense the code from the if-elif-else to something more like a loop? I've heard about dictionary and lists, but that seems too complicated for this I think. For example: "Your 'snicker' is dispensed below" "You 'Kitkat' is dispensed below"

Thanks

How's a dictionary more complicated than what you already have? A dictionary will clean up a lot of your code and get ride of 1/3 of the lines, mostly the elifs

vendingdict = {"A1": ["Snickers", 0.89],
               "A2": ["M&Ms", 1.39],
               "A3": ["Lays", 0.50]}
def main():
    global myselection
    while True:
        myselection=input("Welcome to virtue vending machine!\nMachine only takes $1 bills\nSelect your choice:\n")
        try:
            if vendingdict[myselection] != None:
                break
        except KeyError:
            print("\nPlease input valid selection\n")
            continue

def bills():
    while True:
        try:
            cashin = int(input("Insert your bills: $"))
        except ValueError:
            print("Please insert valid tender!")
            continue
        cashout = 0
        if cashin>=vendingdict[myselection][1]:
            cashout = cashin - vendingdict[myselection][1]
            print("Your change is $%.2f" % cashout)
            print("Your %s is below!" % vendingdict[myselection][0])
            break
        else:
            print("Insufficient money, please insert more.")
            print(cashin)
            cashin = 0
            continue


main()
bills()

Why can't you just send the user input selection to message() as a parameter? Maybe create a dictionary products with user inputs as keys and products as values. Then message(products[userInput]).
