python ttk treeview sort numbers

Question

I\'m trying to use the ttk.Treeview sort function illustrated in the answer to this question (Tk treeview column sort) and it works just fine for strings like \'abc\', \'bcd

Answer 1

I figure I'd add this bit of code for anyone wanting to use the above solution for both regular string sorts and numeric sorts.

def treeview_sort_column(tv, col, reverse):
    l = [(tv.set(k, col), k) for k in tv.get_children('')]
    try:
        l.sort(key=lambda t: int(t[0]), reverse=reverse)
        #      ^^^^^^^^^^^^^^^^^^^^^^^
    except ValueError:
        l.sort(reverse=reverse)

    for index, (val, k) in enumerate(l):
        tv.move(k, '', index)

    tv.heading(col, command=lambda: treeview_sort_column(tv, col, not reverse))
