Hey, I want to run a Python script in my QtCreator C++ project, but what I don't want is something like a python interpreter inside my application. I just would like to switch to Python for doing one specific task in my program. It should take a text file, change some things and save it as a new one, so it has nothing to do with the rest of the program. Is this possible and how? Thansk for answers!

@ Niagarer said in How to use/execute a Python script inside QtCreator C++ project : It should take a text file, change some things and save it as a new one, so it has nothing to do with the rest of the program. Sounds like this could be easily done with c++. Is it worth to plug another language with its whole runtime environment just for that one task? Anyway, If you don't want to embed an interpreter into your app the only other option is to run the interpreter as a separate process. You can use the QProcess class for that. It would require the user to have python interpreter installed. In the simplest case something like this: QStringList arguments { "scriptfile.py", "someotherparam", ... }; QProcess p; p.start("python", arguments); p.waitForFinished();
