def citycord():#按钮定义
root = Tk()
root.title("城市编码")
root.geometry('1000x600')
yscrollbar = Scrollbar(root)
text = Text(root, height=1000, width=600)
yscrollbar.pack(side=RIGHT, fill=Y)
text.pack()
yscrollbar.config(command=text.yview)
text.config(yscrollcommand=yscrollbar.set)
str = """ 可以在代码中替换城市选项(代码中查找Ctrl+F）\n"""
text.insert(END, str)
root.mainloop()
#按钮放置
core = tk.Button (mainwinow, text="城市编码", command=citycore, font=("楷体", 15), width=10, height=1,cursor="spider")
core.place (x=500, y=520)
主窗口用root.Tk(),其他窗口用tk.Toplevel(),
参考代码：
import tkinter as tk
def New_Window():
Window = tk.Toplevel()
canvas = tk.Canvas(Window, height=HEIGHT, width=WIDTH)
canvas.pack()
HEIGHT = 300
WIDTH = 500
ws = tk.Tk()
ws.title("Python Guides")
canvas = tk.Canvas(ws, height=HEIGHT, width=WIDTH)
canvas.pack()
button = tk.Button(ws, text="Click ME", bg='White', fg='Black',
command=lambda: New_Window())
button.pack()
ws.mainloop()
