Question

我在Python 2.7中为幻想足球制作算法，我用它来比较玩家。我在一个类中创建了所有的actor实例，我希望用户能够选择与算法进行比较的实例：

class QB:

    def __init__(self, td, yards, fpts, fptspg, ranking, int):

        self.td = td

        self.yards = yards

        self.fpts = fpts

        self.fptspg = fptspg

        self.ranking = ranking

        self.int = int 


Brady = QB(15,4342,234,21,1,3)
Manning = QB(12,1234,433,12, 2,8)


def alg(userinput):
    alg = X.td*10+X.yards-X.int*10
    print alg

如何让“X”成为用户选择的内容？谢谢！

Answer 1

你可以将你的玩家放入字典：

players = dict(
    Brady=QB(15,4342,234,21,1,3)
    Manning=QB(12,1234,433,12, 2,8)
    )

现在，将alg定义为：

def alg(userinput):
    X = players[userinput]
    alg = X.td*10+X.yards-X.int*10
    print alg

然后它可以被称为：

alg("Brady")

Answer 2

也许和eval功能？

class QB:
    def __init__(self, td, yards, fpts, fptspg, ranking, int):
        self.td = td
        self.yards = yards
        self.fpts = fpts
        self.fptspg = fptspg
        self.ranking = ranking
        self.int = int 


Brady = QB(15,4342,234,21,1,3)
Manning = QB(12,1234,433,12, 2,8)
#print(Brady.td)

def alg(userinput):
    X=eval(userinput)
    alg = X.td*10+X.yards-X.int*10
    print(alg)

.. 实施例

alg("Brady")

结果

或

alg("Manning")

结果

使用raw_input调用实例
