log file during the process of python script

Question

I have python script

test.py

When I run in my Linux via command panel it shows the log (what script is doing)

python test.py

But when I run it in this way I cannot see the log file until the script is done:

nohup python test.py 1> logifle.log 2>&1 &

How I can see the log inside the logfile.log during the script is working?

Does this answer your question? [How to redirect output to a file and stdout](https://stackoverflow.com/questions/418896/how-to-redirect-output-to-a-file-and-stdout) — mkrieger1, Jul 22 '20 at 20:20
Does this help: `stdbuf -oL python test.py 1> logfile.log 2>&1 &` ? — alani, Jul 22 '20 at 20:27
python test.py | tee output.file this just start writing log in the command line — , Jul 22 '20 at 20:35
No i want to have log in the file, not in the command line, i wanna close the commandline and have the active process so when i open the log file i can see what the script is doing — , Jul 22 '20 at 20:53

Use -u flag; from python --help:

-u     : force the stdout and stderr streams to be unbuffered;
         this option has no effect on stdin; also PYTHONUNBUFFERED=x

Need to do this:

nohup python -u test.py 1> logifle.log 2>&1 &
