In bug 1332651 we landed flake8 initial support to lint Python files in the Telemetry directory, by disabling all the detected problems. This bug is about enabling the E302 rule: "expected 2 blank lines, found 1": 1) Remove the E302 rule from the .flake8 file in https://dxr.mozilla.org/mozilla-central/source/toolkit/components/telemetry 2) Run "./mach lint -l flake8 toolkit/components/telemetry". 3) Fix the reported problems

@Alessio I would like to work on this, would please assign me to this ?

(In reply to Deepjyoti Mondal from comment #1) > @Alessio I would like to work on this, would please assign me to this ? Before this bug becomes actionable, we need the dependency (Enabling flake8) to land! :) Once it does, if no problem arises and you have some spare time, I'll gladly do!

okay :)

Enabled flake8 rule E302
