no x=[[0,0,0]]*3 this is still x = [0,0,0] then x[0][0] = 1 x then became [1,0,0] now as x is multiplied it becomes 3 x arrays as [[1,0,0] [1,0,0] [1,0,0]] x[0][0] is behaving like x[0][0] and x[0][0] and x[0][0] or [[x[0][0],0,0]]*3

It is false because x=[[1,0,0],[1,0,0],[1,0,0]] y=[[1,0,0],[0,0,0],[0,0,0]] So x==y is false
