\modulesynopsis{Names for all built-in 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 \samp{from types import *} ---
|
|
the module does not export any names besides the ones listed here.
|
|
New names exported by future versions of this module will all end in
|
|
\samp{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}
|
|
|
|
