Question

我试图制作一个随机组生成器，将学生列表分成几乎相等的分区（例如，如果有11个学生和3个组，我们需要两组四个和一个组3）。我们需要为x次分配重复此过程。我们从文件中读取学生列表，并从文件中读取组。这是我到目前为止的代码：

import csv
import unittest
def studentgenerator(num_asmt, num_stud, student_list, 
assignment_teams):
    with open(student_list , "r") as student:
        list_students = csv.reader(student)

    student_groups = []

    for x in range (0, num_asmt):
        random.shuffle(list_students)
        div = len(list_students)/float(num_stud)


        for x in xrange(num_stud):
            student_groups = lst[int(round(div * x)): int(round(div * 
            (x + 1))]\
   for group in student_groups:
        with open(assignment_teams, "w") as team:
            list_assignment_groups = csv.writer(team)
            list_assignment_groups.writerow(group)



student_list.close()
assignment-teams.close()

我似乎无法让分区程序以我想要的方式运行，而且我认为从文件读取/输出出现问题，但我不确定正是我做错了什么。

Answer 1

您可以定义一个chunker来为您进行拆分。事实上，这是一个真正的“发电机”。由@Ned Batchelder提供（在那里）。

import random

def chunks(l, n):
    """Yield successive n-sized chunks from l."""
    for i in range(0, len(l), n):
        yield l[i:i + n]

n = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K']

random.shuffle(n)

list(chunks(n, 3))
# [['B', 'H', 'G'], ['D', 'A', 'C'], ['E', 'F', 'I'], ['J', 'K']]

Answer 2

import random
while True:
    n    = int(input("Enter the class strength"))
    students = [[i] for i in range(1,n+1)]
    x    = len(students)
    tNum     = 0

    #Nmber of teams
    print('The possible number of teams are')
    for i in range(1, x + 1):
        if x % i == 0:
            print(i)

   y        = int(input("Enter the no of teams"))

   if n == 0 or y == 0:
    print("Enter valid entries please")
    continue        

   z     = int(x/y)

   #Loop
   while x > 0:
       if x%z == 0:
            print("Team",tNum + 1)
            tNum +=1
            choice = random.choice(students)
            students.remove(choice)
            x = len(students)
            print(choice)

   q = input("Do you want to close or continue ? [y/n]")

   if q == "y":
       continue
   else:
       break

使用python制作随机组生成器
