Python in a Nutshell

Name

getfirst

Synopsis

                        f.getfirst(key,default=None)

When f .has_key( key ), and f [ key ].value is a single value, not a list of values, getfirst returns f [ key ].value. When f .has_key( key ), and f [ key ].value is a list of values, getfirst returns f [ key ].value[0]. When key is not a key in f, getfirst returns default.

Use getfirst when you know that there should be just one input field (or at most one input field) named key in the form from which your script’s input comes. getfirst was introduced in Python 2.2, so don’t use it if your script must remain compatible with older versions of Python.
