Hi @gsnidero, thanks for reaching out. The avoid-single-character-names-variables rule is based on the Google Python Style Guide, which we're trying to follow closely, and as a result I think this trigger is correct, so I'm going to close this issue.

If you'd prefer different behaviour, you can disable this rule and instead write your own into your .sourcery.yaml config file - the documentation here and the rule definition here should help get you started.

Hi @bm424, ok – I was thinking at the common use of _ as a "throwaway variable" e.g.. Thank you for the quick reply.
