The \module{operator} also defines a few predicates to test the type

of objects. \strong{Note:} Be careful not to misinterpret the

results of these functions; only \function{isCallable()} has any

measure of reliability with instance objects. For example:

\begin{verbatim}

\end{verbatim}

\begin{funcdesc}{isCallable}{o}

\deprecated{2.0}{Use the \function{callable()} built-in function instead.}

Returns true if the object \var{o} can be called like a function,

otherwise it returns false. True is returned for functions, bound and

unbound methods, class objects, and instance objects which support the

\method{__call__()} method.

\end{funcdesc}

\begin{funcdesc}{isMappingType}{o}

Returns true if the object \var{o} supports the mapping interface.

This is true for dictionaries and all instance objects.

\strong{Warning:} There is no reliable way to test if an instance

supports the complete mapping protocol since the interface itself is

ill-defined. This makes this test less useful than it otherwise might

be.

\end{funcdesc}

\begin{funcdesc}{isNumberType}{o}

Returns true if the object \var{o} represents a number. This is true

for all numeric types implemented in C, and for all instance objects.

\strong{Warning:} There is no reliable way to test if an instance

supports the complete numeric interface since the interface itself is

ill-defined. This makes this test less useful than it otherwise might

be.

\end{funcdesc}

\begin{funcdesc}{isSequenceType}{o}

Returns true if the object \var{o} supports the sequence protocol.

This returns true for all objects which define sequence methods in C,

and for all instance objects. \strong{Warning:} There is no reliable

way to test if an instance supports the complete sequence interface

since the interface itself is ill-defined. This makes this test less

useful than it otherwise might be.
