这里有一段代码，根据我理解你想要的做了以下处理：
import tkinter as tk
from tkinter import ttk
class App(tk.Tk):
def __init__(self):
super().__init__()
self.title('医院管理系统')
self.geometry('250x250')
self.label = ttk.Label(self, text='医院管理系统')
self.label.pack()
if __name__ == "__main__":
app = App()
app.mainloop()
希望这是你想要的。
英文:
Hi here is a code that make what I understand you want :
import tkinter as tk
from tkinter import ttk
class App(tk.Tk):
def __init__(self):
super().__init__()
self.title('HOSPITAL MANAGEMENT SYSTEM')
self.geometry('250x250')
self.label = ttk.Label(self, text='HOSPITAL MANAGEMENT SYSTEM')
self.label.pack()
if __name__ == "__main__":
app = App()
app.mainloop()
Hope it is what you want

在你的主函数中执行以下操作：
- 创建一个根 tkinter 窗口
root=Tk() - 创建一个类的实例并传递对象
Hospital(root) - 当你准备好运行你的应用程序时，调用
root.mainloop()
英文:
Do that in your main function-
- create a root tkinter window
root=Tk() - create an instance of class and pass the object
Hospital(root) - call mainloop when you are ready for your application to run.
root.mainloop()

You are missing mainloop():
您遗漏了mainloop()：
Don't use wildcard import *. Use import tkinter as tk:
不要使用通配符 import *。使用 import tkinter as tk：
Snippet (片段):
import tkinter as tk
class Hospital:
def __init__(self, root):
self.root = root
self.root.title('医院管理系统') # Displayed as 'HOSPITAL MANAGEMENT SYSTEM'
self.root.geometry('400x400')
lbltitle = tk.Label(self.root, bd=20, relief=tk.RIDGE,
text='医院管理系统', # Displayed as 'HOSPITAL MANAGEMENT SYSTEM'
fg='red', bg='white',
font=('times new romain', 50, 'bold'))
lbltitle.pack(side=tk.TOP, fill='x')
if __name__ == "__main__":
app = Hospital(tk.Tk())
tk.mainloop()

Don't use wildcard import *. Use import tkinter as tk
Snippet:
import tkinter as tk
class Hospital:
def __init__(self, root):
self.root = root
self.root.title('Hostipal System Management')
self.root.geometry('400x400')
lbltitle = tk.Label(self.root, bd=20, relief=tk.RIDGE,
text='Hostipal System Management',

lbltitle.pack(side=tk.TOP, fill='x')
if __name__ == "__main__":
app = Hospital(tk.Tk())
tk.mainloop()
