I am new to tkinter and learning to organize the frames in tkinter. In the following code, I have created 3 label frames.

The frames are not aligned as per my requirements and I would like to get help organizing them cleanly.

Required
===========
By default it gives me following layout


      LabelFrame1             LabelFrame2
LabelFrame3


I would like to have left aligned label frames like this:

LabelFrame1 LabelFrame2
LabelFrame3

How to align all label frames to left so that I can have spaces in right?

CodePudding user response：

For greater clarity, first draw on a piece of paper what you want to place in the window.

And you will see that you need to stretch tk.LabelFrame(f, text='Calculator') over several cells ( columnspan=3).

# variables
padding = dict(padx=20, pady=20)
padding_widget = dict(padx=10, pady=5)

ws, hs = win.winfo_screenwidth(), win.winfo_screenheight()  # screen
x, y = -10, hs * 0.1
win.geometry('%dx%d %d %d' % (w, h, x, y))
