Coding Assignment: Maximum Price in a Shopping List

Write a Python program that:

Stores a list of floating-point item prices (e.g., [12.50, 45.00, 8.99, 99.99, 23.40]).
Uses a for loop to iterate through each price in the list.
Compares each price against a running tracker to find and store the highest value.
Prints out the final maximum price neatly.

Expected Output:

Scanning item prices: [12.5, 45.0, 8.99, 99.99, 23.4]

-> Most expensive item found: $99.99
