Introduction to the correct calling method of the Python Interpreter

What should we do if we want to call the Python interpreter in C? In fact, this operation is relatively simple. We can use the sample code below to fully grasp the operation steps to help us get some help in practical applications.

Python interpreter call code example:

 
 

  
  
#include < iostream> 
  
  
#include < string> 
  
  
#include "Python.h"  
  
  
int main()  
  
  
{  
  
  
std::cout < <  "Welcome to SIMPLEPYTHON!!" < <  std::endl;  
  
  
std::cout < <  "Chapter 17, Demo 01 - MUD Game Programming" < <  std::endl;  
  
  
Py_Initialize(); // initialize python  
  
  
std::string str;  
  
  
std::getline( std::cin, str );  
  
  
while( str != "end" )  
  
  
{  
  
  
PyRun_SimpleString( const_cast< char*>( str.c_str() ) );  
  
  
std::getline( std::cin, str );  
  
  
}  
  
  
Py_Finalize(); // shut down python  
  
  
return 0;  
  
  
} 
 
 

The above is the call method for the Python interpreter.
