Tkinter has three built-in layout managers that use geometric methods to position buttons in an application frame: pack, grid, and place. 

• The pack manager organizes widgets in horizontal and vertical boxes that are limited to left, right, top, bottom positions offset from each other.
• The grid manager locates widgets in a two dimensional grid using row and column relative coordinates.  
• The place manager places widgets in a two dimensional grid using x and y absolute coordinates.

How to Position Buttons With Pack

Pack() has three options you can use: side, fill, expand.  

• The side option aligns buttons horizontally.
• The fill option aligns buttons vertically.
• The expand option takes up the full height of the frame.

How to Position Buttons With Grid

Grid() is used to position buttons based on row and column coordinates on a grid in a frame similar to a spreadsheet.

• The row option aligns button horizontally
• The column option alights button vertically

How to Position Buttons With Place

Place() is used to position buttons based on x,y coordinates in a frame.

• The x variable aligns button horizontally
• The y variable aligns button vertically

If you want to take advantage of the latest version of Tkinter, you’ll need to install a version of Python that supports Tcl/Tk 8.5 or greater. This will provide you with the Ttk (Tile extension integrated into Tk), which is required in order to run the current Tk widget set.
