Lothar the main Diagonal is a[i] [i], and I didn't understand which additional diagonal is which. But I tried writing code, thinking a[j][j]. Please check if this is correct. from random import random k=4 a=[] for i in range(k):     z=[]     for j in range(k):         n=int(random()*100)         z.append(n)         print("%4d"%n,end='')     print()     a.append(z) print() for i in range(k):     for j in range(k):         if i==j:             b=a[i][j]             a[i][j]=a[i][k-1-j]             a[i][k-1-j]=b for i in range(k):     for j in range(k):         print("%4d"%a[i][j],end='')     print()

k[1][1] = j[1] k[2][2] = j[2]
