Question

PYTHON very BEGINNERS

I need help with fixing my code, especially the "try/except" part. Thank you.

Here is the desired output:

*Part 1

*Part 2

Here is my code:

from random import *

def getPrice (price):

    #price = round (uniform(0, 100), 2)

    print ("The price is: $" +str (price))

    return float(price)

def calcPayment ():

    price= getPrice(55.77)

   #price= getPrice(87.33)

    payment = float(input("Enter your payment:"))

    change= payment-price

    dues= price-payment

    if payment >= price:

       print ("Here's your change of $" + str(round (change, 2)))

    elif payment < 0:

       print ("Payment must be a positive value larger than price")

    elif payment < price:

       print ("That's not enough. You need $" + str(round(dues, 2))+" more")

# exception handling:

# payment is a string (non-numeric value)

    return payment

    try:

       payment = ????????????

    except: # could not convert string to float

       print ("You must enter a numeric value")

calcPayment ()
