Chromium Python style guide

For other languages, please see the Chromium style guides.

Chromium follows PEP-8 unless an exception is listed below.

See also the Chromium OS Python Style Guidelines.

You can propose changes to this style guide by sending an email to python@chromium.org. Ideally, the list will arrive at some consensus and you can request review for a change to this file. If there's no consensus, //styleguide/python/OWNERS get to decide.

Differences from PEP-8

• Use two-space indentation instead of four-space indentation.
• Use CamelCase() method and function names instead of unix_hacker_style() names.

(The rationale for these is mostly legacy: the code was originally written following Google's internal style guideline, the cost of updating all of the code to PEP-8 compliance was not small, and consistency was seen to be a greater virtue than compliance.)
