Question

这是我的代码：

class People:

    def __repr__(self):
        return f"A('{self.name}', {self.age})"

    def __init__(self, name, age):
        self.name = name
        self.age = age

def sortlist():
    people = []
    file = open('people.txt', 'r').readlines()

    for k in file:
        k = k.split()
        people.append(People(k[0], float(k[1])))
    people.sort(key=lambda c: (c.age, c.name))
    g = 0
    for g in range(len(people)):
        people[g].height = g + 1
return people

def question_height():
    for i in sortlist():
            print(random(i[0]))

def question_name():
    for i in sortlist():
        for i in range(0,104):
            print(random.choice(i.name))

代码的最后一部分（在 return 人之后）没有按照我想要的方式工作。我希望 question_height 函数从 height 属性中选择一个随机数，而 question_name 函数从 name 属性中选择一个随机名称。

有人知道我可以做些什么来让它发挥作用吗？

Answer 1

你只用 random.choice 功能就好了。它需要一系列项目，并随机选择其中一个。首先，您必须将 People 对象列表转换为名称或身高列表。然后，只需将列表传递给 random.choice 函数即可。

def question_height():
    all_heights = [person.height for person in sortlist()]
    print(random.choice(all_heights))

def question_name():
    all_names = [person.name for person in sortlist()]
    print(random.choice(all_names))

另一种选择是将 Person 对象列表直接传递给 random.choice，然后只打印其名称或身高。

def get_random_person(people):
    return random.choice(people)

def question_height():
    people = sortlist()
    random_person = get_random_person(people)
    print(random_person.height)
    
def question_name():
    people = sortlist()
    random_person = get_random_person(people)
    print(random_person.name)
