Your first NumPy array

Once you're comfortable with NumPy, you'll find yourself converting Python lists into NumPy arrays all the time for increased speed and access to NumPy's excellent array methods.

sudoku_list is a Python list containing a sudoku game: 

[[0, 0, 4, 3, 0, 0, 2, 0, 9],
 [0, 0, 5, 0, 0, 9, 0, 0, 1],
 [0, 7, 0, 0, 6, 0, 0, 4, 3],
 [0, 0, 6, 0, 0, 2, 0, 8, 7],
 [1, 9, 0, 0, 0, 7, 4, 0, 0],
 [0, 5, 0, 0, 8, 3, 0, 0, 0],
 [6, 0, 0, 0, 0, 0, 1, 0, 5],
 [0, 0, 3, 5, 0, 8, 6, 9, 0],
 [0, 4, 2, 9, 1, 0, 3, 0, 0]]

You're going to change sudoku_list into a NumPy array so you can practice with it in later lessons, for example by creating a 4D array of sudoku games along with their solutions!

Instructions

  • Import NumPy using its generally accepted alias.
  • Convert sudoku_list into a NumPy array called sudoku_array.
  • Print the class type() of sudoku_array to check that your code has worked properly.
