# List Comprehensions

Let's learn about list comprehensions! You are given three integers X,Y and Z representing the dimensions of a cuboid along with an integer N. You have to print a list of all possible coordinates given by (i,j,k) on a 3D grid where the sum of i+j+k is not equal to N . Here, 0<=i<=X;0<=j<=Y;0<=k<=Z Input … Continue reading List Comprehensions
