If you are using the cgi module and its FieldStorage class, the getlist
method will ALWAYS return a list, even for a single selection.

I do not remember which version of Python added that method, but if you
are using the current version of Python, I think that is the best way to

getfirst is the method to use if you NEVER want a list.  It discards the
extra choices.
