I call a function get_items() which returns a list of items.
However, in some cases, it returns just one item.
It returns the item as an object though, not as a list containing one object.
In other cases it simply returns None.
What is the cleanest way to iterate over the return value of this func

Denis kindly provided the following code which does this well:
def mkiter( x ):
""" list -> list, el -> [el], None -> []
usage: for x in mkiter( func returning list or
singleton ): ...
"""
return (x if hasattr( x, "__iter__" ) # list tuple ...
else [] if x is None
el
