9.6 Code Practice, this is in Python, I need its quick!

def printIt(a):

   for r in range(len(a)):

       for c in range(len(a[0])):

           print(a[r][c], end = " ")

       print(" ")

   print(" ")

   for r in range(len(a)):

       x = a[r][r]

       for c in range(len(a[0])):

           a[r][c] = x

   for r in range(len(a)):

       for c in range (len(a[0])):

           print(a[r][c], end = " ")

       print(" ")

N = []

N.append([1, 2, 3, 4, 5])

N.append([1, 2, 3, 4, 5])

N.append([1, 2, 3, 4, 5])

N.append([1, 2, 3, 4, 5])

printIt(N)
