The following code to enter and print a matrix is printing an 'empty' 2D list instead of what I entered. What error am I making?

Question

matrix = []
n = int(input("Enter the dimensions of the square matrix: "))
temp = []
for i in range(n):
for j in range(n):
temp.append(input(str(i)+str(j)+" "))
matrix.append(temp)
temp.clear()
print (matrix)

Answer 1

Your temp.clear() empties it which is reflected in matrix. Your temp initialization was in wrong place. Updated here:
