Python - Tkinter - using frames to group widgets in row

import tkinter as tk

root = tk.Tk()

main_frame = tk.Frame(root)
main_frame.pack()


fs = [] # list to keep all frames (but I don't use it in this example)


for r in range(10): # (r)ow

    # create frame to keep labels in row
    f = tk.Frame(main_frame)
    f.grid(row=r)

    # keep frame on list to use it later (to move or remove it)
    fs.append( f )

    # add some labels in frame in one row
    for c in range(10): #(c)olumn
        t = '| {}.{} |'.format(r, c)

        l = tk.Label(f, text=t)
        l.grid(row=0, column=c)

    # add button to remove frame
    b = tk.Button(f, text='Delete', command=lambda x=f:x.grid_forget())
    b.grid(row=0, column=10)

root.mainloop()
