  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}
