define discount function

def calculate_discount(price, discount_percent):

Check if the discount is 20% or higher

if discount_percent >= 20:

Calculate the discounted price

    discount_amount = price * (discount_percent / 100)
    final_price = price - discount_amount
    return final_price
else:

If discount is less than 20%, return the original price

    return price

Prompt the user for the original price and discount percentage

try:

original_price = float(input("Enter the original price of the item: "))
discount_percentage = float(input("Enter the discount percentage: "))

Calculate the final price

final_price = calculate_discount(original_price, discount_percentage)

Print the result

if final_price == original_price:
    print(f"No discount applied. The final price is: ${original_price:.2f}")
else:
    print(f"Discount applied! The final price is: ${final_price:.2f}")

except ValueError:
   print("Please enter valid numerical values.")
