Question

我想使用在函数“ func1”内的函数“ take”中启动的self.value的值。但是，尝试这样做时出现错误。

代码：

class all():
    def __init__(self):
        self.temp = self.value # Here I declare it first before the self.new but still get error. May I know why?
        if:
            **func**
        else:
            **func**
        self.new = self.func1()

    def func1(self):
        **func**
        return ["{}".format(self.temp)]

    def take(value):
#In this example, the value already contained some values. and already been called. but in another program not in the same program.
        self.value = value

错误：

AttributeError: "all" object has no attribute "value"

发生此错误的原因是，您未在构造方法（ init ）方法中定义值。

    def __init__(self):
        self.value = 20(example purpose)

在具有来自另一个自我的另一个自我的函数中使用自我时收到错误
