Tkinter 按钮使用网格扩展
Tkinter button expand using grid
我是编码新手，刚开始学习 Python。我搜索了答案，但找不到答案。
我正在尝试制作一个用于学习目的的计算器，但我无法使底部 keyboard frame 展开，或者 buttons 内部展开以匹配根 window 的边界
这是我的代码：
from tkinter import *
# main window configuration
root=Tk()
root.geometry("1000x1000")
root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=1)
# main window frames
topmenu=Frame(root,padx=5,pady=5)
display=Frame(root,padx=5,pady=5)
keyboard=Frame(root,padx=5,pady=5,bg="red")
topmenu.grid(row=0,column=0)
display.grid(row=1,column=0)
keyboard.grid(row=2,column=0)
# topmenu widgets
# display widgets
#keyboard widgets

Question: Tkinter button expand using grid
TkDocs: The Grid Geometry Manager Handling Resize
You are configure only the root to grow:
root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=1)
如果有额外的空间，您还必须将 keyboard 框架配置为 增长，添加：
keyboard.grid_columnconfigure(0, weight=1)
keyboard.grid_rowconfigure(0, weight=1)
您必须配置 每个 keyboard row/column 和 weight=1。
You don't set the keyboard frame to expand
keyboard.grid(row=0,column=0)
改为
keyboard.grid(row=0,column=0, sticky=NSEW)
工作示例：
root=Tk()
root.geometry("500x500")
root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=1)
keyboard=Frame(root,padx=5,pady=5,bg="red")
keyboard.grid(row=0,column=0, sticky=NSEW)
for row, row_buttons in enumerate([['%', '√x', 'x²', '1/x'], ["C", "←", "÷"]]):
keyboard.grid_rowconfigure(row, weight=1)
for col, text in enumerate(row_buttons):
keyboard.grid_columnconfigure(col, weight=1)
Button(keyboard, padx=5, pady=5, text=text).grid(row=row, column=col, sticky='EWNS')
