Shortest code that gives no error with c++ compiler and python interpreter.

I challenge you to find a shorter code that the condition above is met.

#define min main(){}
min

    That does not work because c++ compiler looks for the main function.

    that wouldn't work with python interpreter but for c++ it's the shortest.

This one is 2 bytes shorter:

#define id main(){}
id

    Absolutely! Next thing i want to do is adding some other languages to the statement. I guess all the allowed languages in codeforces could do the job.

    No 1-letter function exists in Python 3.12 so I'm pretty sure this is the shortest.

      Thanks for replying; you brought my attention back to this problem, which caused me to think more about it. Turns out, there is a shorter solution. It uses an entirely different idea. Here it is:

      int
exit();
main()
{}

      This compiles with g++ and runs with Python 3.11 (probably works with 3.12 too). It is 1 byte shorter than my previous solution.

      An even shorter solution can be compiled with gcc as C source code, but doesn't compile with g++ as C++ source code:

      exit();
main()
{}

        With some clever Python semicolon usage, you can reduce this from 24 bytes CRLF/21 bytes LF to 22 bytes CRLF/20 bytes LF.

        int
exit();main()
{}
