function calledprint_matrixthattakes a list and prints in 2D format. The function prints every row on a separate line separated by a tab character. If the input is not a list, the function prints an error message. Assume that if the input is a list then it is a valid matrix, i.e. the number of columns in each row is equal. Note that you should not print a tab after the last item in the row.

Save the function under thefunctions.pyfile. program namedt01.pythat tests the functionprint_matrix.

For this python task there is a functions module and a task module. (simplify code as much as possible). This is a practice problem.
