返回最低分数

Question

这是我的代码，它由多个成员组成小组，然后对每个小组进行评分，然后对它们求和以获得本例中 4 个小组的总分。

import random

def run(members, n_groups):
    participants = list(range(1,members+1))*n_groups
    random.shuffle(participants)

    my_groups = list(zip(*[iter(participants)]*members))
    print(my_groups)

    def get_rating(group):
        return (len(set(group)))

    score = ((sum(get_rating(g) for g in my_groups)))
    print(score)
    return score

members = 4
n_groups = 4

print(min(run(members, n_groups) for _ in range(10)))

输出：

[(3, 3, 4, 1), (4, 2, 3, 1), (2, 3, 2, 4), (1, 1, 4, 2)]
13
[(3, 1, 1, 4), (2, 3, 2, 4), (1, 4, 1, 2), (3, 2, 4, 3)]
12
[(2, 4, 4, 1), (3, 3, 1, 3), (3, 1, 2, 2), (4, 4, 2, 1)]
11
[(3, 1, 4, 1), (3, 1, 2, 1), (2, 2, 4, 4), (3, 2, 3, 4)]
11
[(1, 1, 3, 1), (2, 2, 3, 1), (3, 2, 4, 4), (4, 4, 3, 2)]
11
[(3, 2, 1, 2), (4, 1, 3, 4), (4, 2, 3, 1), (1, 2, 4, 3)]
14
[(2, 4, 3, 1), (3, 4, 4, 2), (1, 1, 2, 1), (3, 3, 4, 2)]
12
[(3, 3, 1, 2), (2, 1, 3, 3), (2, 4, 4, 2), (4, 1, 1, 4)]
10
[(1, 4, 3, 2), (4, 2, 3, 3), (3, 1, 2, 1), (4, 4, 1, 2)]
13
[(2, 4, 1, 3), (3, 2, 2, 3), (1, 4, 1, 3), (1, 4, 2, 4)]
12
10

所以每个组都会得到一个评分，然后最低分数会显示在底部，有没有办法让我重新打印获得最低分数的组？因为如果我尝试使用 100,000 个，我很难检查每一个以找出它来自哪个组！

我试过了：

import random

def run(my_groups, score):
    participants = list(range(1,members+1))*n_groups
    random.shuffle(participants)

    my_groups = list(zip(*[iter(participants)]*members))
    print(my_groups)

    def get_rating(group):
        return (len(set(group)))

    score = ((sum(get_rating(g) for g in my_groups)))
    print(score)
    return score

members = 4
n_groups = 4

print(min(run(members, n_groups) for _ in range(10), key=lambda x:x[1]))

但是这个returns"Generator expression must be parenthesized if not sole argument"为括号运行?

Answer 1

将 run 更改为 return my_groups, score。

然后改变

min(run(members, n_groups) for _ in range(10))

到

min((run(members, n_groups) for _ in range(10)), key=lambda x:x[1])

这使得 min return 是整个 (my_groups, score) 元组，但只比较 score（元组的第二个元素）以找到最小值值。

Answer 2

import random


def run(members, n_groups):
    participants = list(range(1, members + 1)) * n_groups
    random.shuffle(participants)

    my_groups = list(zip(*[iter(participants)] * members))
    return my_groups


def get_rating(group):
    return len(set(group))


def score(my_groups):
    return sum(get_rating(g) for g in my_groups)


best = min(*(run(4, 4) for _ in range(10)),
           key=score)
print(best)
print(score(best))

返回最低分数

Returning min score
