bookChallenge: Tuple Operations

Your grocery store's system is designed to track the inventory of items on different shelves using tuples, as tuples provide a way to ensure the data is immutable once set.

However, the store needs to monitor certain items and track their quantities or positions to assist in restocking or rearranging.

You are tasked with analyzing and managing inventory data using tuples to determine certain metrics and take actions based on specific criteria.

Task

Swipe to start coding

Manage a tuple representing a shelf of fruits by performing operations to count, find, and check stock levels.

  • Count how many times "apples" appear in the shelf tuple. Store this in apple_count and print: "Number of Apples: <$apple_count>".

  • Find the index of the first occurrence of "bananas" in the shelf tuple. Store the index in banana_index and print: "First Banana Index: <$banana_index>".

  • Check if the number of apples is less than 5. If true, print: "Apples need to be restocked." Otherwise, print: "Apples are sufficiently stocked."

  • Count how many times "grapes" appear in the shelf tuple. If grapes appear only once, print: "Grapes need to be restocked." Otherwise, print: "Grapes are sufficiently stocked."

  • Check if "oranges" exist in the shelf tuple. If they do, print their index with: "Oranges are at index: <$orange_index>". If they don't exist, print: "Oranges are out of stock."

Output Requirements

  • Print the number of apples: "Number of Apples: <$apple_count>".
  • Print the index of the first occurrence of bananas: "First Banana Index: <$banana_index>".
  • Print a message about the apple stock status: "Apples need to be restocked." or "Apples are sufficiently stocked."
  • Print a message about the grape stock status: "Grapes need to be restocked." or "Grapes are sufficiently stocked."
  • Print the index of oranges if they exist: "Oranges are at index: <$orange_index>", or "Oranges are out of stock."

Note

You can use the in and not in operators with both tuples and lists.
