Python的GUI各有各特点。
由于只是轻微涉及GUI开发,所以就以轻量级的tkinter来学习。
from tkinter import *

root.title('我的窗口')
root.geometry('500x500')
root.mainloop()
Button所有的可设置参数

#这是一段没有显示Frame 代码
from tkinter import *
root=Tk()
root.geometry('500x500')
frame=Frame(root,height = 200,width = 400,bg = 'black')
Label(frame,text='mylabel').pack()

#下面是探究出缩水原因的代码
from tkinter import *

button2.pack(side=LEFT)
frame.pack(side=TOP)

#下面的是使用.pack_propagate(0)解决了问题的代码
