gcc main.cpp -o main.out
./main.out
The purpose is to execute the main.cpp file from Python3.

look subprocess call
import subprocess
subprocess.run(["gcc", "main.cpp -o main.out"])
subprocess.run(["./main.out"])
should work. But subprocess have more utilities that will be usefull for you.

Thanks for the answer. But I have a compile time error, because I need to link the some .lib files.I can compile in VS because I add the .lib files in the Linker-> Input. So do you know how can I see the cmd Visual Studio uses to compile and execute my code ?

Sorry but I alwais use Linux for programing and I only know the basics about cmd. But subprocces module have options to manage the output, and yo can link the libs withs gcc from the cmd, try -I or -l option.

The argument needs to be either
["gcc", "main.cpp", "-o", "main.out"] or "gcc main.cpp -o main.out". Otherwise subprocess.list2cmdline creates the incorrect command line gcc "main.cpp -o main.out".
