通过java执行python代码将登录信息保存到文件中

Question

I want to execute a python script through java. I used below sample code for that. the problem is when I execute python script through commandline it save logs in to log_test.log file. but when I execute from java logs doesn't write in to the log file I'm using python 3.7 and java 1.8

Python script

import logging

logger = logging.getLogger('log_test')
logger.setLevel(logging.INFO)
fh = logging.FileHandler('log_test.log')
fh.setLevel(logging.INFO)

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

fh.setFormatter(formatter)

logger.addHandler(fh)

logger.info('info message')

Java code

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

import javax.script.ScriptException;

public class Main {

    public static void main(String[] args) throws ScriptException, IOException {


        Process p = Runtime.getRuntime().exec("python ./log_test.py");

        BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));

        System.out.println("output");
        String s = null;
        while ((s = stdInput.readLine()) != null) {
            System.out.println(s);
        }

    }

}

Change Python path and script path to absolute path

And change the file path of logging.FileHandler to the absolute path.
