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: + +\begin{datadesc}{NoneType} +The type of \code{None}. +\end{datadesc} + +\begin{datadesc}{TypeType} +The type of type objects (such as returned by \code{type()}). +\end{datadesc} + +\begin{datadesc}{IntType} +The type of integers (e.g. \code{1}). +\end{datadesc} + +\begin{datadesc}{LongType} +The type of long integers (e.g. \code{1L}). +\end{datadesc} + +\begin{datadesc}{FloatType} +The type of floating point numbers (e.g. \code{1.0}). +\end{datadesc} + +\begin{datadesc}{StringType} +The type of character strings (e.g. \code{'Spam'}). +\end{datadesc} + +\begin{datadesc}{TupleType} +The type of tuples (e.g. \code{(1, 2, 3, 'Spam')}). +\end{datadesc} + +\begin{datadesc}{ListType} +The type of lists (e.g. \code{[0, 1, 2, 3]}). +\end{datadesc} + +\begin{datadesc}{DictType} +The type of dictionaries (e.g. \code{\{'Bacon': 1, 'Ham': 0\}}). +\end{datadesc} + +\begin{datadesc}{DictionaryType} +An alternative name for \code{DictType}. +\end{datadesc} + +\begin{datadesc}{FunctionType} +The type of user-defined functions and lambdas. +\end{datadesc} + +\begin{datadesc}{LambdaType} + An alternative name for \code{FunctionType}. +\end{datadesc} + +\begin{datadesc}{CodeType} +The type for code objects such as returned by \code{compile()}. +\end{datadesc} + +\begin{datadesc}{ClassType} +The type of user-defined classes. +\end{datadesc} + +\begin{datadesc}{InstanceType} +The type of instances of user-defined classes. +\end{datadesc} + +\begin{datadesc}{MethodType} +The type of methods of user-defined class instances. +\end{datadesc} + +\begin{datadesc}{UnboundMethodType} +An alternative name for \code{MethodType}. +\end{datadesc} + +\begin{datadesc}{BuiltinFunctionType} +The type of built-in functions like \code{len} or \code{sys.exit}. +\end{datadesc} + +\begin{datadesc}{BuiltinMethodType} +An alternative name for \code{BuiltinFunction}. +\end{datadesc} + +\begin{datadesc}{ModuleType} +The type of modules. +\end{datadesc} + +\begin{datadesc}{FileType} +The type of open file objects such as \code{sys.stdout}. +\end{datadesc} + +\begin{datadesc}{XRangeType} +The type of range objects returned by \code{xrange()}. +\end{datadesc} + +\begin{datadesc}{TracebackType} +The type of traceback objects such as found in \code{sys.exc_traceback}. +\end{datadesc} + +\begin{datadesc}{FrameType} +The type of frame objects such as found in \code{tb.tb_frame} if +\code{tb} is a traceback object. +\end{datadesc}
