Python:AttributeError:Toplevel1实例没有属性'；入口1'；

python user-interface tkinter

Python:AttributeError:Toplevel1实例没有属性'；入口1'；,python,user-interface,tkinter,Python,User Interface,Tkinter,当我尝试打开Python脚本时，会出现以下错误： Traceback (most recent call last): File "gui.py", line 111, in <module> vp_start_gui() File "gui.py", line 30, in vp_start_gui top = Toplevel1 (root) File "gui.py", line 79, in __init__ self.Button1.co

当我尝试打开Python脚本时，会出现以下错误：

Traceback (most recent call last):
  File "gui.py", line 111, in <module>
    vp_start_gui()
  File "gui.py", line 30, in vp_start_gui
    top = Toplevel1 (root)
  File "gui.py", line 79, in __init__
    self.Button1.configure(command=self.getTemp())
  File "gui.py", line 105, in getTemp
    this.plz = this.Entry1.get()
AttributeError: Toplevel1 instance has no attribute 'Entry1'

我预计这一行还会出现另一个错误：

self.Text1.configure(text="Stadt: " + str(this.json["name"]) + "\nTemperatur: " + str(this.json["main"]["temp"]))

否则它应该运行。我没有向gui脚本添加太多代码

编辑好的，现在我有了完整的工作代码：

您在

\uuuu init\uuuu

中分配了

self.Entry1=tk.Entry（顶部）

。然后通过

getTemp（this）

方法中的

this.Entry1…

引用条目。此操作失败，因为只能在

self

下找到

Entry1

。将所有

this

更改为

self

，应该可以。

您想要的是

self

，而不是

this

self.plz = self.Entry1.get()

这是Python，不是Java。（还要注意，名称

self

作为第一个参数显式传递到方法中。理论上，您可以使用

this

作为名称，而不是

self

，但后者是绝对通用的标准，因此请不要使用。）

更新：

你的线路

self.Button1.configure(command=self.getTemp())

先于

self.Entry1 = tk.Entry(top)

因此，在定义

self.Entry1

之前，正在调用

self.getTemp（）

。
