Getting pylint warning: "No config file found, using default configuration"

Question

$ pylint --reports=n main.py

Output:

No config file found, using default configuration

Answer 1

You will get the "No config file found, using default configuration" warning if you do not have a .pylintrc file in your home directory, or if you don't specify the pylint argument --rcfile=/path/to/pylintrc.

To suppress the message, on *nix:

$ touch ~/.pylintrc

Answer 2

found a pylintrc and using it, works. Posting it here in case anyone needs it. You can Modify it to suit your project.

# generation. It is itself both a raw checker and an astng checker in order
