Python 3:在类中的方法之间共享变量

Question

寻找如何通过一个方法/函数在同一个类中的另一个方法/函数可访问的类中创建一个变量集,而不必在外面做多余的(和有问题的代码).

这是一个不起作用的例子,但可能会告诉你我正在尝试做什么:

#I just coppied this one to have an init method
class TestClass(object):

    def current(self, test):
        """Just a method to get a value"""
        print(test)
        pass

    def next_one(self):
        """Trying to get a value from the 'current' method"""
        new_val = self.current_player.test
        print(new_val)
        pass

Answer 1

您可以在一个方法中设置它,然后在另一个方法中查找它:

class TestClass(object):

    def current(self, test):
        """Just a method to get a value"""
        self.test = test
        print(test)

    def next_one(self):
        """Trying to get a value from the 'current' method"""
        new_val = self.test
        print(new_val)

作为注释,您需要self.test在尝试检索之前进行设置.否则,它将导致错误.我通常这样做__init__:

class TestClass(object):

    def __init__(self):
        self.test = None

    def current(self, test):
        """Just a method to get a value"""
        self.test = test
        print(test)

    def next_one(self):
        """Trying to get a value from the 'current' method"""
        new_val = self.test
        print(new_val)
