Python, please help, please write the code that can run and please show the output, must be in matrix! thank you

Write a Python function sum_diagonal( (M), where M is a square matrix. Function should return the sum of the diagonal elements of the matrix M. Write a Python program that prompts the user to enter the size of a square matrix. Generate a square matrix of size entered by the user. Populate the matrix with random numbers between 4.6 and 16.7 with uniform function in random library (i.e: random.uniform(4.6,16.7)) Seed the random number generator with 206. Round the elements of the matrix to 3 significant figures after the decimal point. Your program should call the function sum_diagonal and prints out the sum of the diagonal elements of a given matrix
