Python 如何打印属于单个数组的两个类变量？

我在Python中有两个类变量，例如澳大利亚人和美国人，它们有相同的属性，但是是分开的，所以我可以区分这两个。我将它们组合成一个数组，根据年龄对它们进行排序。现在我希望如下所示显示它们，但我正在努力找到一种方法来实现它。我对Python脚本非常陌生，并且还在学习

class Aus(object):
    def __init__(self, Name, Age, Height):
        self.Name = Name
        self.Age = Age
        self.Height = Height

class US(object):
    def __init__(self, Name, Age, Height):
        self.Name = Name
        self.Age = Age
        self.Height = Height

John = Aus("John", 22, 153)
Steve = Aus("Steve", 15, 180)
Henry = PC("Henry", 20, 192)
Tim = PC("Tim", 85, 160)
Aussies = [John, Steve, Henry, Tim]

Mary = US("Mary", 21, 178)
Sue = US("Sue", 80, 159)
Americans = [Mary, Sue]

Total = Aussies + Americans
Total.sort(key=lambda x: x.Age, reverse=True)

我希望结果是这样的

Tim -> 85 Years/160 cm
Sue -> 80 Years/159 cm
John -> 22 Years/153 cm
Mary -> 21 Years/178 cm

等等

有没有办法做到这一点？

一种方法是定义自己的

\uuuu str\uuuu

：

请注意，我假设Henry和Tim也是澳大利亚人：

class Intro(object):
    def __str__(self):
        return "%s -> %s Years/%s cm" % (self.Name, self.Age, self.Height)

class Aus(Intro):
    def __init__(self, Name, Age, Height):
        self.Name = Name
        self.Age = Age
        self.Height = Height

class US(Intro):
    def __init__(self, Name, Age, Height):
        self.Name = Name
        self.Age = Age
        self.Height = Height

John = Aus("John", 22, 153)
Steve = Aus("Steve", 15, 180)
Henry = Aus("Henry", 20, 192)
Tim = Aus("Tim", 85, 160)
Aussies = [John, Steve, Henry, Tim]

Mary = US("Mary", 21, 178)
Sue = US("Sue", 80, 159)
Americans = [Mary, Sue]

Total = Aussies + Americans

然后将排序后的

与
str
一起使用：

[str(s) for s in sorted(Total, key=lambda x:x.Age, reverse=True)]

输出：

['Tim -> 85 Years/160 cm',
 'Sue -> 80 Years/159 cm',
 'John -> 22 Years/153 cm',
 'Mary -> 21 Years/178 cm',
 'Henry -> 20 Years/192 cm',
 'Steve -> 15 Years/180 cm']

几乎所有的工作都是你自己做的。我对你的代码做了一些小的修改，我认为这是最好的做法

class Person(object):
    def __init__(self, Name,Age,Height,Country):
        self.Name = Name
        self.Age = Age
        self.Height = Height
        self.Country = Country

John = Person("John", 22, 153,"Australia")
Steve = Person("Steve", 15, 180,"Australia")
Henry = Person("Henry", 20, 192,"Australia")
Tim = Person("Tim", 85, 160,"Australia")
Aussies = [John, Steve, Henry, Tim]

Mary = Person("Mary", 21, 178,"US")
Sue = Person("Sue", 80, 159,"US")
Americans = [Mary, Sue]

Total = Aussies + Americans
Total.sort(key=lambda x: x.Age, reverse=True)
for i in Total:
    print(i.Name + " -> " + str(i.Age) + " Years/" + str(i.Height) + "cm")

输出

您的类属性（名称、年龄等）应为小写，请参阅
Tim -> 85 Years/160cm
Sue -> 80 Years/159cm
John -> 22 Years/153cm
Mary -> 21 Years/178cm
Henry -> 20 Years/192cm
Steve -> 15 Years/180cm
