42. A file named item_cost, dat is stored on a computer's hard drive. In a text editor the file displays the first few lines of the file below. The rest of the file is not shown. Write a Python program that reads the contents of this file, determines the most expensive item and prints the information about that item and its cost to the screen using the format shown below. Write your code using standard file I/O commands; do not use any csv reader available in some Python package. Do not use any built-in sorting functions.

Example output: The most expensive item is Item57 and costs \$5.26
