Python in a Nutshell

Name

getlist

Synopsis

                        f.getlist(key)

When f .has_key( key ), and f [ key ].value is a single value, not a list of values, getlist returns [ f [ key ].value], i.e., a list whose only item is f [ key ].value. When f .has_key( key ), and f [ key ].value is a list of values, getlist returns f [ key ].value. When key is not a key in f, getlist returns the empty list [].

Use getlist when you know that there can be more than one input field named key in the form from which your script’s input comes. getlist was introduced in Python 2.2, so don’t use it if your script must remain compatible with older versions of Python.
