Align Tkinter radio buttons

Question

My Tkinter radio buttons are misaligned. I have tried this Python tkinter align radio buttons west , this Python tkinter align radio buttons west and none of them worked, what I see is this

when I use grid to manage the widgets (has to be grid as it is part of a larger UI).

I have tried anchor, and justify but got tracebacks that those were not allowed:

Code

import tkinter as tk

root = tk.Tk()

value = tk.IntVar()
value.set(0)  # initializing the choice, i.e. mrads


def get_traj_method():
    print(value.get())

tk.Label(root, text="""T method:""", justify = tk.LEFT, padx = 20).grid(row=0)

tk.Radiobutton(root, text='T_Deviation', padx = 20, variable=value, command=get_traj_method, value=0).grid(row=1, sticky=tk.E)
tk.Radiobutton(root, text='T_Degrees', padx = 20, variable=value, command=get_traj_method, value=1).grid(row=2, sticky=tk.E)

root.mainloop()

Answer 1

Put sticky = "W", instead of tk.E( tk.W should work too)

The widgets have different sizes, so when locking them to the east(right) the ends align, but the beginnings ( in this case the button) will not be aligned.

When putting sticky = "W" the situation is the reverse. :

import tkinter as tk

root = tk.Tk()

value = tk.IntVar()
value.set(0)  # initializing the choice, i.e. mrads


def get_traj_method():
    print(value.get())

tk.Label(root, text="T method:", justify = tk.LEFT).grid(row=0)

tk.Radiobutton(root, text='T_Deviation', variable=value, command=get_traj_method, value=0).grid(row=1, sticky="W")
tk.Radiobutton(root, text='T_Degrees', variable=value, command=get_traj_method, value=1).grid(row=2, sticky="W")

root.mainloop()
