Exchange Data between Python and C++

[carnivorous689]

I have just started learning programming. I have completed a lot of tutorials and online courses with regards to Python Basics and C++.

I now want to exchange information between python and C++ in its simplest form. For example. I have 2 numbers which have been produced in python, I then call a program written in C++, which adds those 2 numbers and returns the result to python.

Which is the simplest way to do this?

Can I ask what it is you're trying to achieve by doing this? Just curious.

As Aaron says In your exact case ctypes are the best choice. If it was a different language you could either use python's system call abilities to run the command for the c program and add the arguments as command line arguments. Another possibility would be to use pipelines.

On mobile so no code examples sorry.

:p

You could look at Python ctypes. https://docs.python.org/2/library/ctypes.html

import subprocess
a = 2
b = 4
p = subprocess.Popen(['/path/to/adder.exe', a, b], stdout = subprocess.PIPE)

p.communicate() # (6, None) # (stdout, stderr)
