Python 在创建GUI时遇到问题

python user-interface tkinter

Python 在创建GUI时遇到问题,python,user-interface,tkinter,Python,User Interface,Tkinter,我正在做计算机科学作业，但遇到了问题。任务是创建一个带有按钮的gui，该按钮打开一个新窗口并显示来自Swapi的信息（可在www.Swapi.co上找到）我的问题是，它说我缺少位置参数，无法找出它们缺少的地方，或者我使用tkinter模块为Gui做了什么错误，我还导入了一个我创建的类。程序和类都位于下面 from tkinter import * from People import Person def FormatToString(collection): results

如果您使用

Person.openstarship（starship）

，则将其作为静态方法运行，而不是类方法，因此它不使用

self

，并通知您缺少值

您应该使用decorator

@staticmethod

并删除

self

    @staticmethod
    def openwindow(starships):

或者您必须创建类

Person

person_instance = Person(...put values...)
Button(..., command=person_instance.openwindow(starship))

但是

command=

还有其他错误。它需要不带

（）

和

参数的函数名，之后它将使用（）来运行此函数。要使用参数指定方法，可以使用
lambda`
Button(..., command=lambda:person_instance.openwindow(starship))

但在循环中创建的command=
中使用参数需要使用新变量从原始变量复制访问权限，而原始变量将在下一个循环中被覆盖
Button( command=(lambda x=starships:Person.openwindow(x)) )


其他问题：GUI应该只有一个使用Tk（）
创建的主窗口。要创建其他窗口，请使用Toplevel（）
。在其他GUI框架中也可以类似
所有GUI框架都使用主循环（也称为事件循环
），并且在所有GUI框架中应该只有一个主循环-在tkinter
中，它是tkinter.mainloop（）


还有其他建议，但不是错误：

import*
不是首选，最好使用import tkinter
或非常流行的import tkinter as tk
。然后你必须使用tk.tk（）
，tk.Button（）
，等等
方法/函数应具有小写\u名称
-ie.get\u home\u world（）
格式化为字符串


您可以在中看到的所有建议

请分享错误始终将完整的错误消息（从单词“Traceback”开始）作为文本（不是截图）进行讨论（不是评论）。还有其他有用的信息。您应该只使用Tk（）
来创建主窗口。对于其他窗口，请使用Toplevel（）
阅读如果您使用Person.openstarship（starship）
，则它应该是使用decorator@staticmethod
创建的静态方法，而不使用def openstarship（starship）
中的self。它给了你缺少的论点。
