Python 属性错误：'_tkinter.tkapp'；对象没有属性'；文本'；在特金特

我设置了一个天气应用程序，但当我点击按钮获取天气时，我得到了这个错误？在这个应用程序中，我创建了

线程

，用于进行后台处理。 在这里，我试图在另一个函数中获取

self.text

值和访问权限

请，我能理解。

self.weather图标

需要

self.text

，它是在

self.get\u weather

中创建的，因此

self.get\u weather

必须在

self.weather图标

之前运行，并且

self.weather图标

必须等待

self.get\u weather

结束其工作-确保

self.text

已存在

最好将两个函数中的代码放在一个函数中，并在一个线程中运行

    city = self.city.get()
    thread = Thread(target=self.get_weather_and_icon, args=(city,))

    thread_weather_icon.start()

    # autocomplete location
    try:
        auto_url = f"http://dataservice.accuweather.com/locations/v1/cities/autocomplete?apikey={self.api}&q=" + city
        data = requests.get(auto_url).json()
        check = ''

    self.icon['image'] = self.photo

哪里是self.text=…？您没有

self.text

，因此不能将其用作参数。我有。你又看到了代码。现在我看到你在

self.get_weather

中看到了它，但是它是在

线程（target=self.weather\u图标，args=（self.text，）

之后执行的，所以

self.text

创建得太晚了。您必须首先运行self.get_weather并等待它创建self.text是否正确：

text=self.text

！你必须先运行self.get_weather并等待它创建self.text，然后运行Thread（target=self.weather_图标，args=（self.text，）我们能在一个人身上见面吗？
