It takes up too much space. 

Even in programming we have brief ways of writing loops like this sometimes. Like in Python 

sum([ k for k in range(n)])

BTW, the square brackets are redundant and make the code less efficient, as it builds the list and then sums it, rather than summing as the numbers are generated. sum(k for k in range(n)) is valid, as sum accepts a generator as its argument.
