TIPS

1. 例外処理含む評価パターンを追加

import pprint, sys, time

def core(arg, adv=True):
    n = arg
    if adv:
        ret = int(n * (n + 1) / 2 + 1)
    else:
        ret = 1 + sum(range(n + 1))
    return ret

def app(*args):
    ret = []
    for arg in args:
        s = []
        for adv in [False, True]:
            st = time.time()
            try:
                r = core(arg, adv=adv)
            except Exception as e:
                r = e
            s.append([adv, round(time.time() - st, 6), r])
        ret.append([arg, s])
    return ret

print(sys.version)
pprint.pprint(app(
    # basic examples
    1,
    3,
    # additional examples
    0,
    10000,
    # exceptional examples
    "例外入力"
))
