声明一个类People,成员变量有姓名，出生日期，性别，身高，体重等；生成10个类对象，并放在一个一维数组中，编写方法按身高进行排序

好的，我会尽力回答您的问题。下面是代码示例：

class People:
    def __init__(self, name, birthday, gender, height, weight):
        self.name = name
        self.birthday = birthday
        self.gender = gender
        self.height = height
        self.weight = weight

people_list = [People("张三", "1990-01-01", "男", 175, 65),
               People("李四", "1992-02-02", "女", 170, 60),
               People("王五", "1995-03-03", "男", 180, 70),
               People("赵六", "1998-04-04", "女", 165, 50),
               People("钱七", "2000-05-05", "男", 185, 75),
               People("孙八", "2002-06-06", "女", 160, 45),
               People("周九", "2005-07-07", "男", 190, 80),
               People("吴十", "2008-08-08", "女", 155, 40),
               People("郑十一", "2010-09-09", "男", 195, 85),
               People("冯十二", "2012-10-10", "女", 150, 35)]

def sort_by_height(people_list):
    return sorted(people_list, key=lambda x: x.height)

sorted_people_list = sort_by_height(people_list)
for p in sorted_people_list:
    print(p.name, p.height)

以上代码中，我们定义了一个`People`类，包含了姓名、出生日期、性别、身高和体重等属性。我们创建了一个包含10个`People`对象的列表`people_list`，并使用`sorted()`函数按照身高进行排序，返回一个新的排序后的列表`sorted_people_list`。最后我们遍历打印排序后的列表中每个人的姓名和身高。

希望能对您有所帮助！
