Is it possible to name output of files in python?

Question

Is it possible to name every output of files and display it in one single console?

Let's say I have a main.py file and a main.java file, and I want to run them both in one Python script and seperate the outputs by naming them.

Now I have a python file and it should do this:

# run main.py
# run main.java

# when an output is sent from a file, it should be like this:
output = "{} > {}".format(file, output)
# and then print the output.

Let's say the java file would usually display Hello, World! but here it would be like this in the console: main.java > Hello, World!

Thanks!

EDIT:

1. I gave a java and a python file as an example, I just want to name the output of different files, without modifying them.
2. I wanted to run them both as a subprocess and display the outputs with names in one console.

Let's say main.java file contains:

class main {
    public static void main(String[] args) {
        System.out.println("Hello, World! from Java");
    }
}

and main.py file:

print("Hello, World! from Python")

You can do it by using subprocess module in another Python file:

import subprocess

java = "{} > {}".format("main.java", subprocess.run("java main.java", shell=True, capture_output=True, text=True).stdout.strip())
print(java)
python = "{} > {}".format("main.py", subprocess.run("python main.py", shell=True, capture_output=True, text=True).stdout.strip())
print(python)

The output will be:

main.java > Hello, World! from Java

main.py > Hello, World! from Python
