在函数中使用self时接收到错误，该函数具有来自另一个s的另一个self

Question

我想使用self.value的值，这是我在“func1”的函数内部的函数“take”中初始化的。但是，我在尝试这样做时收到了一个错误

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"

Answer 1

出现此错误的原因是，您没有在构造函数（init）方法中定义值

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