I've used pm2 for my Node.js script and I love it.
Now I have a python script which collect streaming data on EC2. Sometimes the script bombs out and I would like a process manager to restart itself like pm2.

Is there something the same as pm2 for python? I've been searching around and couldn't find anything.

Here's my error

That I would like it to just restart itself in case something happens.

You can actually run python scripts from within pm2:

pm2 start echo.py

If the script ends in a .py suffix it will use a python interpreter by default. If your filename doesn't end in .py you can do:

pm2 start echo --interpreter=python

I've found you have to be a little bit careful which python you are using, especially if you are using a virtualenv python with a different version to the 'default' python on your machine.
