  • 将班级人数(比如21)随机分成三组

    # random split a list such as the number of a class
    
    import random 
    
    
    # equal random split a list
    def randomEqualSplit(mylist, n):
        resultList = [] # create result list
        part = round(len(mylist)/n) # calculate the part 
        for i in range(n): # for every part 
            extract = random.sample(mylist, part) # extrat one part 
            for i in extract : # for every element 
                if i in extract: # if the element in the list 
                    mylist.remove(i) # remove the element form the list
            resultList.append(extract) # add the extract element to a empty list
        return resultList # return the list
    
    result = randomEqualSplit([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21],3) # create the object of the function
    print(result) # print the result

    目标是将一个列表随机分成了3份,来源于开题时,需要将全班人数分成三组,但是谁都不想在第一组。

    主要用到了一个random.sample(),其他的指示没有用到。
