Introduction to the function list in the Python Module

If you encounter some incomprehensible questions about the Python module during the actual application process of the Python module, you can use our article to provide a relatively good answer to the Python module related questions, the following is an introduction to the specific content of the article. I hope you will gain some benefits.

Modules and functions use the PyImport_Import () function in Python/C APIs to import Python modules to C Programs. The PyImport_Import () function returns a module object. The function prototype is as follows.

 
 

  
  
PyObject* PyImport_Import( PyObject *name)  
 
 

The parameter meanings are as follows. Name: name of the module to be imported. Using the PyObject_CallObject () and PyObject_CallFunction () functions in Python/C APIs, you can call the functions in the Python module in the C program. The parameter prototypes are as follows.

 
 

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

For the PyObject_CallObject () function, the parameter meanings are as follows. Callable_object: The function object to be called. Args: list of parameters in the format of tuples. The parameter meanings of PyObject_CallFunction () are as follows. Callable_object: The function object to be called. Format: Specifies the parameter type. Parameters passed to the function.

Use the PyModule_GetDict () function in Python/c api to obtain the function list in the Python module. The PyModule_GetDict () function returns a dictionary. The keyword in the dictionary is the function name and the value is the call address of the function. The function prototype is as follows.

 
 

  
  
PyObject* PyModule_GetDict( PyObject *module)   
 
 

The above is an introduction to the practical application of Python modules and functions.
