<span>Tier 1 Tier 1 providers have the largest and fastest network connections available. A reasonable definition of a tier 1 provider is a network that can reach every other network on the Internet without purchasing IP transit or paying for peering. You might consider a Tier 1 network to be an ISP for other ISPs. Because of their extremely good connectivity, other network providers pay Tier 1 networks to carry their data for them to other locations. As of this time, there are less than 20 Tier 1 network providers worldwide.</span>

Write a Python program to: ask the user to enter the price of an item. Note: use a while loop to check the validity of the price
garik1379 [7]

Answer:

Hi there Tonyhh! Please find the implementation below.

Explanation:

You can save the below code in a file called "price_discount.py". The code is implemented in python 2.0+. To make it work in Python 3.0+, simply update the code to use "input" rather than "raw_input".

price_discount.py

def calculate_discount(price, quantity):

 total = 0.95 * price * quantity;

 return total;

price = raw_input("Enter a price: ");

try:

 price = int(price);

 while price <= 0:

   print("Input a valid number: ")

   price = raw_input("Enter a price: ");

 quantity = raw_input("Enter a quantity: ");

 try:

   quantity = int(quantity);

   if quantity >= 10:

     print(calculate_discount(price, quantity));

 except ValueError:

   print("Invalid quantity!")

except ValueError:

 print("Invalid input!");

 price = -1;
