Question

我使用这个系统制作20个数字为1-20的组，然后对每个组进行评分以查看其随机化程度如何。（1,1,1,1）= 1，因为只有一种类型的数字，其中（1,2,3,3）= 3，因为有3个不同的数字。此代码使用较小的数字并对它们进行排名。然而，当我达到20时，即使我的团队声明有超过10个不同的数字，评级系统最大值为10？谁能明白为什么这会让评级系统达到10？

import numpy
import random
members=20
n_groups =20
participants=list(range(1,members+1))*n_groups
#print participants 
random.shuffle(participants)

with open('myfile1.txt','w') as tf:
    for i in range(n_groups):
        group = participants[i*members:(i+1)*members]
        for participant in group:
            tf.write(str(participant)+' ')
        tf.write('\n')

with open('myfile1.txt','r') as tf:
    g = [list(map(int, line.split())) for line in tf.readlines()]
    print(g)


my_groups =g

def get_rating(group):
    """
    (tuple of ints)->int
    """
    group_str = ""
    for each_num in group:
        group_str += str(each_num)
    return len(set(group_str))

for each_grp in my_groups:  
    print(get_rating(each_grp))

输出： [[6,11,11,7,16,3,1,11,10,16,14,15,14,20,15,12,1,12,15,1]，[15,5,7， 6,9,11,3,1,5,17,9,19,10,1,20,18,3,2,5,18]，[20,11,1,18,5,5,2， 4,14,10,18,1,7,17,9,11,14,16,3,12]，[19,13,1,16,16,14,7,6,5,11,19， 1,1,1,20,2,12,5,19,8,4]，[4,5,10,18,10,16,13,12,5,19,10,16,3,2,10， 4,2,17,2,8]，[19,9,8,5,1,3,8,11,18,20,19,15,6,15,15,2,8,7,6， 18]，[4,2,3,8,2,18,13,14,14,3,8,12,10,17,9,19,10,20,13,2]，[4,9， 17,20,12,2,10,6,6,19,3,17,6,2,2,8,14,3,6,6]，[9,16,5,3,9,16， 11,4,13,13,20,20,17,19,18,12,15,13,14,16]，[11,16,9,18,5,3,13,19,16,12， 7,7,20,10,12,13,20,17,4,10]，[20,5,3,11,15,4,15,11,10,13,14,2,17,14， 9,9,14,6,4,13]，[4,7,19,15,19,13,11,1,4,15,18,10,2,10,1,8,4,8] 9,7]，[10,10,6,1,16,1,11,18,17,9,16,12,16,11,11,1,18,19,4,13]，[12， 13,19,7,5,8,20,15,17,14,8,8,13 8,12,4,18,2,20,7]，[8,5,12,2,12,5,6,12,14,9,19,1,18,17,16,10,16， 5,3,4]，[4,3,13,7,3,4,5,6,5,5,7,4,1,12,17,1,15,6,18,9]，[ 9,15,3,17,20,14,8,12,1,14,13,8,6,1,15,9,19,12,18,3]，[7,7,14,3， 11,14,20,17,6,11,17,2,9,9,17,14,2,16,7,11]，[13,8,4,15,8,16,13,19， 19,18,6,15,18,17,16,20,20,7,9,10]，[17,15,2,7,7,7,13,20,8,6,10,17， 1,12,15,20,6,18,19,11]] 8 9 10 10 10 9 8 9 10 10 9 9 9 9 10 9 10 8 10 9

注意：每个支架的最终数量越低越好，但是如果我算一些人手动更多的话，似乎最大值为10

另一个系统：导入numpy 随机导入成员= 20 n_groups = 20 参与者名单=（范围（1，成员+ 1））* n_groups #print参与者 random.shuffle（参加者）

with open('myfile1.txt','w') as tf:
    for i in range(n_groups):
        group = participants[i*members:(i+1)*members]
        for participant in group:
            tf.write(str(participant)+' ')
        tf.write('\n')

with open('myfile1.txt','r') as tf:
    g = [list(map(int, line.split())) for line in tf.readlines()]
    print(g)


my_groups =g

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

Answer 1

get_rating功能未正确实施。例如，考虑get_rating((1, 11))的输出。您的函数将所有数字连接在一起以获得'111'并返回唯一字符数（1）。只有十个十进制数字，所以这是你的最大值。

只需简化代码即可避免此问题：

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

无需将数字转换为字符串。

评级系统限制为10
