Answer 1

Answer:

Explanation:

First te square list l is created using nested loops, whenever i equals j, 1 is appended , otherwise 0 is appended to the row. temp list denotes each row which is finally appended to the l everytime after inner loop exits.

Then, another nested loop is used to print the square list as mentioned below.

Please provide comments if you have any doubts!

Code:

1 = 11 for i in range(5): temp = [] for j in range(5): if(i==j): temp.append(1) else: temp.append() 1.append(temp) for i in range(5): for j in range(5): print(1[i][j], end = ' ') print)

l = []

for i in range(5):
temp =[]
for j in range(5):
if(i==j):
temp.append(1)
else:
temp.append(0)
l.append(temp)

for i in range(5):
for j in range(5):
print(l[i][j], end = ' ')
print()

  

Output:

1OOOO 01000 OO 100 OOO 10 OOOO 1 . . .Program finished with exit code 0 Press ENTER to exit console.
