 If you expect this possibility
 (when your HTML form contains multiple fields with the same name), use
! the \function{isinstance()} built-in function to determine whether you
! have a single instance or a list of instances. For example, this
 code concatenates any number of username fields, separated by
 commas:
 
 \begin{verbatim}
! value = form.getvalue("username", "")
! if isinstance(value, list):
! # Multiple username fields specified
! usernames = ",".join(value)
! else:
! # Single or no username field specified
! usernames = value
 \end{verbatim}

 If you expect this possibility
 (when your HTML form contains multiple fields with the same name), use
! the \function{getlist()} function, which always returns a list of values (so that you
! do not need to special-case the single item case). For example, this
 code concatenates any number of username fields, separated by
 commas:
 
 \begin{verbatim}
! value = form.getlist("username")
! usernames = ",".join(value)
 \end{verbatim}
