Tkinter: How to set size for empty row or column in grid().

As default empty row/column has height/width 0 (zero) and you don't see this row/column but it exists.

import tkinter as tk

root = tk.Tk()

l1 = tk.Label(root, text='Col:8 Row:1', bg='red')
l1.grid(column=8, row=1)

l2 = tk.Label(root, text='Col:1 Row:8', bg='red')
l2.grid(column=1, row=8)

root.mainloop()

You could put Label with spaces and new lines (\n) as text

import tkinter as tk

root = tk.Tk()

l1 = tk.Label(root, text='Col:8 Row:1', bg='red')
l1.grid(column=8, row=1)

l2 = tk.Label(root, text='Col:1 Row:8', bg='red')
l2.grid(column=1, row=8)

# add empty label in row 0 and column 0
l0 = tk.Label(root, text='     \n   ', bg='green')
l0.grid(column=0, row=0)

# add empty label in row 9 and column 9
l9 = tk.Label(root, text='     ', bg='green')
l9.grid(column=9, row=9)

root.mainloop()

Or Label without text but with width/height

import tkinter as tk

root = tk.Tk()

l1 = tk.Label(root, text='Col:8 Row:1', bg='red')
l1.grid(column=8, row=1)

l2 = tk.Label(root, text='Col:1 Row:8', bg='red')
l2.grid(column=1, row=8)

# add empty label in row 0 and column 0
l0 = tk.Label(root, width=3, height=3, bg='green')
l0.grid(column=0, row=0)

l0 = tk.Label(root, width=3, height=3, bg='green')
l0.grid(column=9, row=9)

root.mainloop()

but both use width/height in chars, not pixels.

You can set minimal size for row or column (ie. row/column number 9) using

root.rowconfigure(9, minsize=30)
root.columnconfigure(9, minsize=30)

root.rowconfigure(9, {'minsize': 30})
root.columnconfigure(9, {'minsize': 30})

import tkinter as tk

root = tk.Tk()

l1 = tk.Label(root, text='Col:8 Row:1', bg='red')
l1.grid(column=8, row=1)

l2 = tk.Label(root, text='Col:1 Row:8', bg='red')
l2.grid(column=1, row=8)

# set minimal size for row 9 and column 9
root.rowconfigure(0, minsize=30)
root.rowconfigure(9, minsize=30)

root.columnconfigure(0, minsize=30)
root.columnconfigure(9, minsize=30)

root.mainloop()

Notes:

If you use grid() in other widget ie. frame.grid(...) then you have to use frame.rowconfigure(...) and frame.columnconfigure

Tkinter: How to use Radiobutton and grid() to create clickable calendar.

This simple example shows how to use Radiobutton and grid (and datetime) to create calendar for one month.

It also shows how to use command= in Radiobutton to execute function which changes text in few Labels

Because command= expects callback - it means function's name without () and arguments - so I use …
