This article shows you how to operate Python modules and functions. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Modules and functions

Use the PyImport_Import () function in Python/C API to import the Python module in a C program. The PyImport_Import () function returns a module object. The function prototype is shown below.

PyObject* PyImport_Import (PyObject* name)

The meaning of the parameters is as follows. Name: the name of the module to import. Using the PyObject_CallObject () function in Python/C API and the PyObject_CallFunction () function, you can call functions in Python in a C program. The parameter prototypes are shown below.

PyObject* PyObject_CallObject (PyObject* callable_object, PyObject* args) PyObject* PyObject_CallFunction (PyObject* callable, char * format,...)

For the PyObject_CallObject () function, the arguments mean the following.

Callable_object: the function object to be called.

Args: a list of parameters in tuple form.

For the PyObject_CallFunction () function, the arguments mean the following.

Callable_object: the function object to be called.

Format: specifies the type of parameter.

The argument passed to the function.

Use the

PyModule_GetDict ()

Function to get a list of functions in the Python module.

PyModule_GetDict ()

Function returns a dictionary. The keyword in the dictionary is the function name and the value is the calling address of the function. The function prototype is shown below.
