Question

I want to execute a code helloword.cpp which takes in some argument from console parses those arguments and then prints “hello world” in the console.

Now, I want to parse these arguments from a python scripts parsearguments.py

So for example:

def parse_arguments:
  ...# some code
  return arguments

Now, how do i communicate between python and c++.
I have been reading and see that cython, boost python are the options but I have a hard time finding the right simple hello world example.

Any suggestions will be appreciated.
Thanks

How about passing whatever text you generate with Python into the standard input of your C++ program? Basically, you have to use Python’s subprocess module to fire up the C++ program and dump the text into its standard output.

In case that your C++ program is required to be running separately in the background, you could try another form of interprocess communication, like unix domain sockets.

Using boost::python is also an option, but it might be a little more difficult to deal with.
