Hi,
I'm a student to 1st semester and I have a problem to solve:
"Create a 5x5 random number table and calculate the sum of items per line, per column, and the sum of the elements in the diagonal table. Save the results to a text file."
This is my code until to the sum of items per line. After that I'm stuck!

import random

f=[]
 
for i in range (5):
    line = []
    for j in range (5):
        line.append(random.randint(1,10))
    f.append(line)
 
for each in f:
    print(each)
    print (sum(each))

If anyone knows please reply.
Thanks in advance,
gmit
