python - How to give default argument if starred expression is empty -


i have function call tkinter optionmenu, looks this:

tk.optionmenu(container, targetvar, *list(accountmap))

accountmap dictionary of values i'd appear in optionmenu, in scenarios may dictionary empty, meaning starred expression doesn't return arguments, , function call optionmenu complains not enough arguments have been given. how can add default value of empty string if starred expression returns nothing?

*(accountmap or [""])

the list redundant.
