No output on nohup.out when running a python program in the background

Python when you run it as a background process, it keeps the buffers to itself and does not output anything to your nohup.out, I was stuck at this problem for hours until jk helped me! The solution is to just use python -u

Yup that's it!

So instead of nohup python filename.py & use nohup python -u filename.py &

Few more important commands:

Getting a list of processes  
ps -ax | grep python

Force kill a process
kill -9 processid
