\section{Standard Module \sectcode{types}}
|
|
\stmodindex{types}
|
|
|
|
\renewcommand{\indexsubitem}{(in module types)}
|
|
|
|
This module defines names for all object types that are used by the
|
|
standard Python interpreter (but not for the types defined by various
|
|
extension modules). It is safe to use ``\code{from types import *}'' ---
|
|
the module does not export any other names besides the ones listed
|
|
here. New names exported by future versions of this module will
|
|
all end in \code{Type}.
|
|
|
|
Typical use is for functions that do different things depending on
|
|
their argument types, like the following:
|
|
|
|
\begin{verbatim}
|
|
from types import *
|
|
def delete(list, item):
|
|
if type(item) is IntType:
|
|
del list[item]
|
|
else:
|
|
list.remove(item)
|
|
\end{verbatim}
|
|
|
|
The module defines the following names:
|
