| \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} |
| |
| The module defines the following names: |
| |
| \begin{datadesc}{NoneType} |
| The type of \code{None}. |
| \end{datadesc} |
| |
| \begin{datadesc}{TypeType} |

| \function{type()}\bifuncindex{type}). |
| \end{datadesc} |
| |
| \begin{datadesc}{IntType} |
| The type of integers (e.g. \code{1}). |
| \end{datadesc} |
