modifying tag for the item in tkinter treeview

Question

is there any way I could modify the the tkinter treeview item tag? I know how to create item with tag with insert command, but when I:

tree.set(tree.selection()[0],0,'some text in red', tags='red')

I get TypeError: set() got an unexpected keyword argument 'tags'

The ultimate goal is to change row or column colors... Thanks!

The documentation on Treeview (here for instance) says that there is a method called item that can be used to set or retrieve the options of a tree item.

• tree.item(iid, "tags") returns the list of tags of the item identified by iid

• tree.item(iid, tags="red") changes the tags of iid to ("red",). You can also pass a tuple of tags like tags=("bold", "red").
