Disable invalid name arguments pylint

Question

I have code like this:

def func(df):
    return df.column[0]

I am running pylint and it gives me this message all the time because it flags df as an invalid name despite it's convention.

C:210, 9: Invalid variable name "df" (invalid-name)

Where 210 refers to the row number (not the message code)

Pylint seems to say I can exclude messages by id type but:

1. It doesn't seem to list the message id, just the row and column numbers
2. I don't see where I would exclude messages for a specific variable name but not warnings for other variable names.

In your pylintrc file you can define a good-names variable with a comma seperated list of acceptable names that would otherwise fail the regex.

# Good variable names which should always be accepted, separated by a comma
good-names=i,j,df

If you do not already have a pylintrc file for your project you can generate a template to start with by running:

pylint --generate-rcfile > pylintrc
