put a Button into a frame in python tkinter -

i trying template tkinter application. cant put buttons frames.

is frame right control use template? or there different.

from tkinter import *  root = tk()  frame = frame(root, height="200", width="200", bg="green").pack() b = button(frame, text="hell world").pack(padx="10", pady="10")  z = label(root, text="outside").pack()  root.mainloop() 

this code.

the code runs, button beneath green frame. want have button inside of frame.

is possible?

frame = frame(root, height="200", width="200", bg="green").pack() 

after line executes, frame equal none because that's pack() returns. need assign widget , pack on separate lines if want keep reference it.

frame = frame(root, height="200", width="200", bg="green") frame.pack() 

same b , z, never use them don't matter much.
