Is there a way to append a blank item to a list? I don't want to append the value None, but really nothing.
Ex.
>>> a = [1,2,3,4]
>>> a.append(None)
>>> a
#what I would like to happen
[1,2,3,4]
#what happens
[1,2,3,4,None]
Ex.
>>> a = [1,2,3,4]
>>> a.append(None)
>>> a
#what I would like to happen
[1,2,3,4]
#what happens
[1,2,3,4,None]
