- Create a file named minesweeper.py Create a function that takes a grid of # and -, where each hash (#) represents a mine and each dash (-) represents a mine-free spot. Return a grid, where each dash is replaced by a digit, indicating the number of mines immediately adjacent to the spot i.e. (horizontally, vertically, and diagonally). Example of an input: [ ["-", "-", "-", "#", "#"], ["-", "#", "-", "-", "-"], ["-", "-", "#", "-", "-"], ["-", "#", "#", "-", "-"], ["-",","-","-"-"]] Example of the expected output: [ ["1", "1", "2", "#", "#"], ["1", "#", "3", "3", "2"], ["2", "4", "#", "2", "0"], ["1", "#", "#", "2", "0"], ["1", "2", "2", "1", "0"] ] Use deep copy to copy your input grid to make your output grid look the same.Exercise 4: Solve the programming exercise P10.8 on Page 535 on the book.
