在Python中使用变量创建类的实例

我之前发过帖子，但不是很清楚，我在回答问题时遇到了麻烦。自从我编辑它以使其更有意义以来，人们似乎一直没有看它，也许是因为他们看到它已经有了6个答案。所以我把它重新贴在这里：

我对Python和编程还是个新手，所以我需要简单的解释！我甚至不知道你说的字典是什么

我想给我妹妹做一个游戏。这是一种虚拟宠物的东西，宠物有玩具可以玩

我创建了一个类玩具，想要创建一个函数，getNewToyname，data1，data2，data3，data4，data5

我希望这个函数能够创建一个新的类Toy实例，并且每次创建一个新实例时都能够多次调用这个函数

根据我的经验，您创建的实例具有：

class Toy:
    def __init__(self, name, data1, data2, data3, data4, data5):
        pass

myToy = Toy(myToy, 1, 2, 3, 4, 5)

然后将类中的方法用于：

myToy.method1()

鉴于我希望能够拥有多个玩具，每个玩具都有一个playWith方法，我希望每次调用一个玩具时，实例都能反映出玩具的名称

class Toy:
    def __repr__(self):
        return "<type Toy name=%s>" % self.name

我希望每次调用getNewToy方法时实例都不同，。。。以及反映名称的实例

记住，我是编程新手，所以你可以保持简单的解释

非常感谢，现在更容易理解了

创建一个特殊的getNewToy函数没有意义。只需创建类：

 newtoy = Toy(name, data1, data2, data3, data4, data5)

这就是你需要做的

方法我希望实例在每次调用玩具时反映玩具的名称

class Toy:
    def __repr__(self):
        return "<type Toy name=%s>" % self.name

我不明白你为什么需要getNewToy方法。每次调用Toy时，都会得到一个新的类实例。您可能需要这样的代码：

class Toy: 
    def __init__(self, name, data1, data2, data3, data4, data5): 
        self.name = name
        self.data1 = data1
        # ...

myToy = Toy("firsttoy", 1, 2, 3, 4, 5)
myToy2 = Toy("2ndToy", 6, 7, 8, 9, 10)

myToy = Toy("firsttoy", 1, 2, 3, 4, 5)
myToy2 = Toy("2ndToy", 6, 7, 8, 9, 10)

下面是我将如何做你解释的事情：

# The following two classes are toys, both have a playWith 
# as you wanted, each playWith do different things
class Ball:
    def __init__(self):
        self.name = "ball"

    def playWith(self):
        print "the ball bounces"

class Car:
    def __init__(self):
        self.name = "car"

    def playWith(self):
        print "the car is fast"

# This is a Python generator, every time .next() is called on it,
# the next "yield-value" is returned
def generator():
    while True:
        yield Ball()
        yield Car()

# This is the creator, it has to be a class rather than a function
# since you wanted a new toy each time getNewToy is called
# and as such the generator needs to be tracked
class ToyCreator:
    def __init__(self):
        self.generator = generator()

    def getNewToy(self):
        return self.generator.next()

# Create five toys, print their name and play with them
# Do note here that even though we ask for five toys but only have
# two "yields" in the generator, the generator "wraps around" (since,
# internally, its just an endless loop) 
toyCreator = ToyCreator()
for i in range(5):
    toy = toyCreator.getNewToy()
    print "Toy",i,toy.name,"\t:",
    toy.playWith()

更准确地说，你要做的是实现a，a

以下是我将如何按照你的解释行事：

# The following two classes are toys, both have a playWith 
# as you wanted, each playWith do different things
class Ball:
    def __init__(self):
        self.name = "ball"

    def playWith(self):
        print "the ball bounces"

class Car:
    def __init__(self):
        self.name = "car"

    def playWith(self):
        print "the car is fast"

# This is a Python generator, every time .next() is called on it,
# the next "yield-value" is returned
def generator():
    while True:
        yield Ball()
        yield Car()

# This is the creator, it has to be a class rather than a function
# since you wanted a new toy each time getNewToy is called
# and as such the generator needs to be tracked
class ToyCreator:
    def __init__(self):
        self.generator = generator()

    def getNewToy(self):
        return self.generator.next()

# Create five toys, print their name and play with them
# Do note here that even though we ask for five toys but only have
# two "yields" in the generator, the generator "wraps around" (since,
# internally, its just an endless loop) 
toyCreator = ToyCreator()
for i in range(5):
    toy = toyCreator.getNewToy()
    print "Toy",i,toy.name,"\t:",
    toy.playWith()

> P>你可能总是有5个数据项，但即使如此，也要考虑使用*ARG:

class Toy:
    def __init__(self, name, *args):
        self.name = name
        self.data = args

哦，事实上，第二次在第三次左右你会得到相同的答案，因为你的问题没有改变。但是这次人们让不太懂编程的人更容易理解！Jasper，继续检查你之前的问题，寻找新的答案。哦，事实上，第二次你会在第三次左右得到相同的答案，因为你的问题没有改变。但是这一次人们让不太懂编程的人更容易理解！贾斯珀，继续检查你之前的问题，寻找新的答案。
