Tkinter is used to develop GUI (Graphical User Interface) applications. It supports a variety of widgets as well as a variety of widgets methods or universal widget methods.
grid_location() method -
This method returns a tuple containing (column, row) of any specified widget. Since this method is a widget method you cannot use it with master object ( or Tk() object). In order to use this method, you should first create a Frame and treat it as a parent (or master).
Syntax: widget.grid_location(x, y)
Parameters:
x andy are the positions, relative to the upper left corner of the widget (parent widget).
In below example, grid_location() is used to get the location of the widget in the Frame widget.

This method is used to get the total number of grids present in any parent widget. This is a widget method so one cannot use it with master object. One has to create a Frame widget.
Syntax: (columns, rows) = widget.grid_size()
Return Value: It returns total numbers of columns and rows (grids).
Below is the Python code-

Every time you click the mouse button it will return the same value until more widgets are not added OR number of rows and columns are not increased.
