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:

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

Not a direct duplicate, but check this question and answer. When you get the output from Java using this approach, you can format it however you want. — Yevhen Kuzmovych

Could you clarify what you mean by "run them both in one Python script"? Do you mean spawning the Java application as a sub process? — Brian61354270

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

This is great! I appreciate your help, but this code waits for the file to be finished and then displays all the output at the same time, is it possible to display the "live output", but still with the prefix??
