One thought on “Udacity – Intro to Computer Science – Python – Identity Matrix Grid”
I just did this problem, here’s what I got:
def is_identity_matrix(grid):
n = len(grid)
for e in grid:
if n != len(e):
return False
i = 0
while i < n:
j = 0
if grid[i][i] != 1:
return False
while j < n:
if i != j:
if grid[i][j] != 0:
return False
j += 1
i += 1
return True
