• Recently wrote a number of back-end code, the main achievement verification code is sent to the designated mailbox.
• As part of the write send mail using c ++, the code more complicated, written in python before, the use of third-party libraries, e-mail on the matter a few lines of code.
• So I want to be able to call python with c ++ program ah, Baidu, really can, but find that you need to do some work, and this invocation numerous bug.
• So think of following this approach.
• First, the packaging code into an executable program python
• Then let c ++ to execute the executable program, the perfect solution, eliminating a lot of trouble.
• Specific examples are as follows: First, to write with a python helloworld.py, as follows:

import sys
arg = sys.argv[1:]
if len(arg) < 1:
	print("argumen is less!")
	sys.exit(0)
name = arg[0]#从命令行读取参数
print("Hello",name)
sys.exit(0)

• Then package it into an executable program helloworld.
  

  • If not able to find pyinstaller, can be installed using pip ( pip install pyinstaller), the installation is still prompted to restart the terminal.

#include <iostream>
using namespace std;
int main()
{
    system("./helloworld XiaoMing");
	return 0;
}

• After the package is over, the dist/extra will be a next helloworld, take it out and put test.cpp the same directory.
• Then use c ++ (test.cpp) to call it.
