If this can't resolve your problem
如果这不能解决您的问题
button.pack(side=TOP)
You'll need to use the method
您将需要使用该方法
button.grid(row=1,col=0)
the values of row=1,col=0depend of the position of the other widget in your window
值row=1,col=0取决于窗口中其他小部件的位置
or you can use .place(relx=0.5, rely=0.5, anchor=CENTER)
或者你可以使用 .place(relx=0.5, rely=0.5, anchor=CENTER)
button.place(relx=0.5, rely=0.5, anchor=CENTER)
Example using .place():
使用示例.place()：
from tkinter import * # Use this if use python 3.xx
#from Tkinter import * # Use this if use python 2.xx
a = Button(text="Center Button")
b = Button(text="Top Left Button")
c = Button(text="Bottom Right Button")
a.place(relx=0.5, rely=0.5, anchor=CENTER)
b.place(relx=0.0, rely=0.0, anchor=NW)
c.place(relx=1.0, rely=1.0, anchor=SE)
mainloop()
