Instead of passing everything on the command line you may also choose to have a config file. You can configure errors to ignore but also files to exclude.
This is what our
.flake8 file looks like;
# W291 - we dont care about trailing whitespace
# E302 - one line between functions is fine
ignore = W291,E302
exclude = ignore_this.py
ignore_this.py file merely contains an import statement that is not used.
import pandas as pd
This is not a good python file to have lying around but it does demonstrate how flake8 can be configured to ignore certain files.
