Thank you for your quick replies Mats and erky.
I use .get() to retrieve a number from an entry box, which looks like {1} (no
'' marks). If I then turn this number into a set then the result is {'1'}.
num = self.entry_grid[row][col].get()
self.solution[row][col] = set([num])
As I say, my project worked perfectly with just {1} until I discovered a bug
further on in the code. Perhaps I should go back to my original version and the
fix the bug in some other way?
I did try {int(num)} but that resulted in an error that said something along
the lines of int not being iterable. I'll have another look at that idea.
