Can you write me a python program that allows a user 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.

Can you write me a python program that allows a user 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.
