Ah sorry the task is to make a function for this:
def tTable(n): 
tTable(n),even n, returns the initial triangular n-1 x n-1(triangular table i posted before) table as a list of lists. For example, tTable(4) returns [[1, 2, 3], [3, 4], [5]].

Sorry if i was a bit vague, but i don't know how to explain it any better :(. And thanks for the tips! I will definitely read up on it when i get the time.
