TypeError: 'Weather' object is not callable
TypeError: 'Weather' object is not callable
我是编程新手，所以如果我缺少正确的术语，请原谅。
我正在尝试从网站检索图像，然后 post 使用 tkinter 将其放到 GUI 上。它可以工作，因为它 post 是 GUI 上的图像；但是它仍然会根据此 post.
的标题产生错误
导致错误的代码部分如下：
raw_data = BeautifulSoup(urllib.request.urlopen("http://www.weather.com.au/act/canberra").read())
image = raw_data("img", ("class", "si"))[0]
image = image["src"]
if image == ("/images/icons/5.gif"):
URL = urllib.request.urlopen("http://www.weather.com.au/images/icons/5.gif").read()
b64_data = base64.encodestring(URL)
image = PhotoImage(data = b64_data)
label = Label(self, image = image).grid(row = 1, column = 2)
self(image)
进一步缩小范围，似乎第 39 行导致了错误。
self(image)
完整节目如下：
#!/usr/bin/env python
from tkinter import *
import sys
import urllib.request
from urllib.request import urlopen
import base64
from bs4 import BeautifulSoup
class Weather(Frame):
def __init__(self, master):

master.title("Weather Program")
app = Weather(master)
master.mainloop()
我要补充一点，如果网站更新了它的图片并且它不再是“5.gif”（很有可能是天气图标），那么图片将不会显示。
如有任何帮助或指导，我们将不胜感激。我看了高处和低处，但无济于事。提前谢谢你。
包含 self(image) 的行不正确。 'self' 不是 class，它是一个对象。所以，如果你想创建一个 Weather 类型的对象并将一些东西传递给它的构造函数，只需调用 Weather(image).
您不能像调用函数那样调用对象。当您在代码中说 self(image) 时，您正在尝试调用该对象。如果你想这样做，你需要实现 __call__ 方法。但是，我已经对您的示例进行了编码并对其进行了更改。请运行吧。希望对你有帮助
