Detailed Description

Fetch and hold an error which was already set in Python. An instance of this is typically thrown to propagate python-side errors back through C++ which can either be caught manually or else falls back to the function dispatcher (which then raises the captured error back to python).

Unless stated otherwise, the following C++ functions behave the same as their Python counterparts.

Function Documentation

globals()

dict pybind11::globals ( )

inline

Return a dictionary representing the global variables in the current execution frame, or __main__.__dict__ if there is no frame (usually when the interpreter is embedded).

isinstance() [1/2]

template<typename T , detail::enable_if_t< std::is_base_of< object, T >::value, int > = 0>

bool pybind11::isinstance

(

handle

obj

)

\rst Return true if obj is an instance of T. Type T must be a subclass of object or a class which was exposed to Python as py::class_<T>. \endrst

isinstance() [2/2]

bool pybind11::isinstance ( handle  obj, handle  type  )

inline

Return true if obj is an instance of the type.

len_hint()

size_t pybind11::len_hint ( handle  h )

inline

Get the length hint of a Python object. Returns 0 when this cannot be determined.
