Python indentation mismatch for the pylintrc file and what described in python style guide

[mhaoli]

The external python style guide says indentation should be 4 spaces:

3.4 Indentation
Indent your code blocks with 4 spaces.

The style guide also provides an pylintrc file:

2.1 Lint
Run pylint over your code using this [pylintrc](https://google.github.io/styleguide/pylintrc).

While in the pylintrc file, following configuration sets indentation to 2 spaces:

# String used as indentation unit.  The internal Google style guide mandates 2
# spaces.  Google's externaly-published style guide says 4, consistent with
# PEP 8.  Here, we use 2 spaces, for conformity with many open-sourced Google
# projects (like TensorFlow).
indent-string='  '

So which indentation should we use?

thanks for highlighting this. it should be 4 spaces in the pylintrc.

although it's becoming moot with pylint slowly dropping support for formatting related checks and pushing people to use black.
