title: Communication between C++ and Python
body: <p>I am looking for an efficient and smart way to send data between a C++-program and a Python-script. I have a C++ program which calculates some coordinates in-real-time 30Hz. And I wanna access these coordinates with a Python-script. My first idea was to simply create a .txt-file and write the coordinates to it, and then have Python open the file and read. But I figured that it must be a smarter and more efficient way using the RAM and not the harddrive. </p>
  
  <p>Does anyone have any good solutions for this? The C++ program should write 3coordinates (x,y,z) to some sort of buffer or file, and the Python program can open it and read them. Ideally the C++-program overwrites the coordinates every time and there's no problem with reading and writing to the file/buffer at the same time.</p>
  
  <p>Thank you for your help</p>
