我正在从事计算机科学作业，但遇到麻烦，任务是使用一个按钮创建gui，该按钮会打开一个新窗口并显示Swapi API（位于www.swapi.co上）的信息，我的问题是它说我缺少位置争论，并且无法使用tkinter模块找出它们在哪里丢失或我为Gui im做错了什么，我也正在导入一个类，我将该程序和该类都放在下面

答案 0 :(得分：0)
如果使用Person.openstarship(starship)，则将其作为静态方法而不是类方法运行，因此它不使用self，并且会告知您缺少值。
您应该使用装饰器@staticmethod并删除self
@staticmethod
def openwindow(starships):
或者您将不得不创建类Person的实例
person_instance = Person(...put values...)
Button(..., command=person_instance.openwindow(starship))
但是command=还有其他错误。它需要没有()和arguments and later it will use（）to run this function. To assign method with argument you can use lambda`的函数名。
Button(..., command=lambda:person_instance.openwindow(starship))
但是在循环创建的command=中使用参数需要使用新变量来复制原始变量的访问权限，该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框架中可以类似。
所有GUI框架都使用主循环（也称为event loop），并且在所有GUI框架中应仅是一个主循环-在tkinter中，它是tkinter.mainloop()
还有其他建议，但它们不是错误：
import *不是首选，最好使用import tkinter或非常流行的import tkinter as tk。然后，您必须使用tk.Tk()，tk.Button()等。
方法/功能应具有lower_case_names-即get_home_world() format_to-string。
