Practical application of Python modules and functions

The Python module is also widely used in the application of computer languages. The following article introduces the Python module in practical application, the following is a detailed description of the article, and I hope you will learn from it.

Modules and functions

You can use the PyImport_Import () function in the Python/c api to import the Python module to the C program. 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 functions in Python in C Programs. 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

 
 

  
  
PyModule_GetDict() 
 
 

Function to obtain the function list in the Python module.

 
 

  
  
PyModule_GetDict()  
 
 

The 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)
