Lab 7 Submit a flowchart, pseudocode, and python code for the problem statement below. Problem Statement Yabe Online Auctions requires its sellers to post items for sale for a six-week period during which the price of any unsold item drops 12 percent each week. For example, an item that costs .00 during the first week costs 12 percent less, or .80, during the second week. During the third week, the same item is 12 percent less than .80, or .74. Design a modular program that allows a user to input prices until an appropriate sentinel value is entered and displays the price of each item for weeks one through six.

Problem Statement
Yabe Online Auctions requires a program that allows sellers to post items for sale for a six-week period. Price tags on unsold items decrease weekly by 12%. The program should calculate and display the price adjustment for each week.
Flowchart
The flowchart below illustrates the process of the program. It includes the major components such as input, process, and output for weekly price calculations.

Pseudocode
The pseudocode for the auction price calculation program is as follows:
```
1. START
2. DEFINE constant REDUCTION_RATE = 0.12
3. DEFINE variable price
4. INITIALIZE sentinel_value = -1
5. PROMPT user to enter price
6. WHILE price != sentinel_value DO
7. PRINT "Price for week 1: ", price
8. FOR week FROM 2 to 6 DO
9. price = price * (1 - REDUCTION_RATE)
10. PRINT "Price for week ", week, ": ", price
11. END FOR
12. PROMPT user to enter price
13. END WHILE
14. PRINT "Exiting program"
15. END
```
Python Code
The following Python code implements the pseudocode provided above. Each function serves a specific purpose to ensure modularity.
```python
REDUCTION_RATE = 0.12
def display_prices(price):
print(f"Price for week 1: ${price:.2f}")
for week in range(2, 7): # Weeks 2 to 6
price *= (1 - REDUCTION_RATE)
print(f"Price for week {week}: ${price:.2f}")
def main():
sentinel_value = -1 # Sentinel value to exit the loop
while True:
try:
price = float(input("Enter the price of the item (or -1 to exit): "))
if price == sentinel_value:
print("Exiting program")
break
display_prices(price)
except ValueError:
print("Invalid input! Please enter a numeric value.")
if __name__ == "__main__":
main()
```
Explanation of the Code
1. Constants and Functions:
The program begins by defining constants and functions to modularize code for clarity. `REDUCTION_RATE` is defined globally for easy adjustment in the future.
2. Display Prices Function:
A function `display_prices(price)` calculates the weekly price based on the input price. It takes the original price as an argument and prints the price for each of the six weeks.
3. Main Function:
The `main()` function handles user input and program flow:
- It prompts the user to enter the price or a sentinel value, `-1`, to exit.
- If the input is the sentinel value, the program terminates.
- Input validation is implemented using a `try-except` block to handle non-numeric inputs.
4. Error Handling:
The program includes error handling to maintain robustness by catching exceptions related to invalid user inputs.
Conclusion
The Yabe Online Auctions price calculation program successfully demonstrates the principles learned in the course, including modular programming, input handling, and basic mathematical operations. This program caters specifically to the needs of an auction platform while maintaining adaptability and usability for users.
