Answer to Question #196485 in Python for Naren

Question

m, n = input('Enter the values of M and N separated by a space: ').split()

m = int(m)

n = int(n)

matrix_str = input('Enter all matrix values separated by a space: ').split()

matrix = [matrix_str[n*i:n*(i+1)] for i in range(m)]

for i in range(n):

for j in range(i+1):

try:

print(matrix[j][i-j],end=' ')

except:

break

print('')

for i in range(1,m):

for j in range(i+1):

try:

print(matrix[i+j][-1-j],end=' ')

except:

break

print('')

In this answer why did we use for i in range(m) while getting the matrix

Answer 1

for i in range(m) - It takes element from matrix_str row wise that's why we use that.
