I have only implemented it into my additon section so far. But I am trying to print the mean of each row and each column? If that is possible but I am still wrapping my head around the axis's. Any tips or advice would be awesome.

 numpy_list = []
    length_list = 9
    print("Please enter 9 numbers multiples of 2.")
    for i in range(length_list):
        numpy_list.append(float(input("Enter that number!\n")))
    numpy_list = np.array(numpy_list)
    print(np.floor(numpy_list))
    print("\n")

    numpy_list2 = []
    length_list2 = 9
    print("Please enter 9 more numbers for a second matrix. Remember multiples of 2!\n")
    for j in range(length_list2):
        numpy_list2.append(float(input("Enter that number NOWWW!\n")))
    numpy_list2 = np.array(numpy_list2)
    print(np.floor(numpy_list2))
    print("\n")

    print(numpy_list.reshape(3, 3))
    print("\n")
    print(numpy_list2.reshape(3, 3))
    print("\n")

    selection = 0
    while selection != 5:

        selection = int(input("What would you like to do to the matrices?\n"
                      "1: Add\n"
                      "2: Subtract\n"
                      "3: Multiply\n"
                      "4: Element to element multiplication\n"
                      "5: To exit.\n"))

        if selection == 1:
            added = numpy_list + numpy_list2
            print(added.reshape(3, 3))
            print("This is the transpose: \n", np.transpose(added).reshape(3, 3))
            added_col_ave = np.mean(added, axis=0)
            print("The average of the columns is:", added_col_ave)
            added_row_ave = np.mean(added, axis=0)
            print("The average of the rows is:", added_row_ave)

This is what I am currently working with.
