Does anybody know if it's possible to put two lines of text in a single row using grid in TKinter?
If I make the font small enough, can I distribute the text in two lines?
You can put multiple items in one cell but it is highly unusual, may have surprising behavior, and there are better ways to accomplish the same effect.
For example, the grid is invisible so you can have as many rows as you want to achieve any look you can imagine. Also, the definition of "item" is pretty loose -- you can create a frame, and in that frame put two labels, and that frame can go in a single row using grid to give the appearance of two lines of text in a single grid row. You can also use a text widget which lets you put as many lines of text that you want.
