The Program i am trying to create will allow users to enter and validate their phone number and zipcode+4. Then the user will enter values of two, 3x3 matrices and then select from options including, addition, subtraction, matrix multiplication, and element by element multiplication. You should use numpy.matmul() for matrix multiplication (e.g. np.matmul(a, b) ). The program should compute the appropriate results and return the results, the transpose of the results, the mean of the rows for the results, and the mean of the columns for the results. When entering data, the application should use regular expressions and/or Pandas functionality to check the format of the phone number and zipcode. You should check that each value is numeric for the matrices. The user interface should continue to run until the user indicates they are ready to exit. If an inappropriate entry is detected, the program should prompt for a correct value and continue to do so until a correct value is entered. I have already had to scrap my code twice now. Is there a way someone can help me build this and understand what I am doing wrong?
