IT 280 Lab #5: Dictionary Validation Lab

Instructions

Program Inputs:

A Chess Validation Dictionary (user created)

A chessboard.

The text discusses how to describe a chessboard.

Program Processing:

Validate the chess board for each validation item.

Program Output:

Print the results of each validation item.

e.g.

Fail: Number of black pieces 18 black pieces.

Pass: Number of white pieces 12 white pieces.

Pass: Kings One of each color.

Etc.

Please correct/fix the following python code to execute the dictionary validation chessboard and carry out the programs output as outlined above:

Correct/fix the above python coding for Chess Validation Dictionary (chess board) and run the corrected coding in python.

Please post a screenshot of the code in python and write the corrected codes on Chegg using the appropriate python indentations.
