Reflection¶

PyObject *PyEval_GetBuiltins(void)¶

Return value: Borrowed reference. Part of the Stable ABI.

Deprecated since version 3.13: Use PyEval_GetFrameBuiltins() instead.

Return a dictionary of the builtins in the current execution frame, or the interpreter of the thread state if no frame is currently executing.

PyObject *PyEval_GetLocals(void)¶

Return value: Borrowed reference. Part of the Stable ABI.

Deprecated since version 3.13: Use either PyEval_GetFrameLocals() to obtain the same behaviour as calling locals() in Python code, or else call PyFrame_GetLocals() on the result of PyEval_GetFrame() to access the f_locals attribute of the currently executing frame.

Return a mapping providing access to the local variables in the current execution frame, or NULL if no frame is currently executing.

Refer to locals() for details of the mapping returned at different scopes.

As this function returns a borrowed reference, the dictionary returned for optimized scopes is cached on the frame object and will remain alive as long as the frame object does. Unlike PyEval_GetFrameLocals() and locals(), subsequent calls to this function in the same frame will update the contents of the cached dictionary to reflect changes in the state of the local variables rather than returning a new snapshot.

Changed in version 3.13: As part of PEP 667, PyFrame_GetLocals(), locals(), and FrameType.f_locals no longer make use of the shared cache dictionary. Refer to the What’s New entry for additional details.

PyObject *PyEval_GetGlobals(void)¶

Return value: Borrowed reference. Part of the Stable ABI.

Deprecated since version 3.13: Use PyEval_GetFrameGlobals() instead.

Return a dictionary of the global variables in the current execution frame, or NULL if no frame is currently executing.

PyFrameObject *PyEval_GetFrame(void)¶

Return value: Borrowed reference. Part of the Stable ABI.

Return the attached thread state’s frame, which is NULL if no frame is currently executing.

See also PyThreadState_GetFrame().

PyObject *PyEval_GetFrameBuiltins(void)¶

Return value: New reference. Part of the Stable ABI since version 3.13.

Return a dictionary of the builtins in the current execution frame, or the interpreter of the thread state if no frame is currently executing.

Added in version 3.13.

PyObject *PyEval_GetFrameLocals(void)¶

Return value: New reference. Part of the Stable ABI since version 3.13.

Return a dictionary of the local variables in the current execution frame, or NULL if no frame is currently executing. Equivalent to calling locals() in Python code.

To access f_locals on the current frame without making an independent snapshot in optimized scopes, call PyFrame_GetLocals() on the result of PyEval_GetFrame().

Added in version 3.13.

PyObject *PyEval_GetFrameGlobals(void)¶

Return value: New reference. Part of the Stable ABI since version 3.13.

Return a dictionary of the global variables in the current execution frame, or NULL if no frame is currently executing. Equivalent to calling globals() in Python code.

Added in version 3.13.

const char *PyEval_GetFuncName(PyObject *func)¶

Part of the Stable ABI.

Return the name of func if it is a function, class or instance object, else the name of funcs type.

const char *PyEval_GetFuncDesc(PyObject *func)¶

Part of the Stable ABI.

Return a description string, depending on the type of func. Return values include “()” for functions and methods, “ constructor”, “ instance”, and “ object”. Concatenated with the result of PyEval_GetFuncName(), the result will be a description of func.
