Python Coding

Problem 6. Define a function first_rpt(M) which takes as input a NumPy matrix M, and outputs a matrix in which every row of M has been replaced with the first row. For example, the output of first_rpt(my_matrix), where my._matrix is the matrix de- fined directly above, should be the matrix array ([[1, 2, 3, 4], [1, 2, 3, 4], [1, 2, 3, 4]]) Hint: Your function should contain a for loop, which loops over the number of rows in a matrix. Use len(M) to determine how many rows are in the matrix M
