+# Chromium Python style guide
+
+_For other languages, please see the [Chromium style
+guides](https://chromium.googlesource.com/chromium/src/+/master/styleguide/styleguide.md)._
+
+Chromium follows [PEP-8](https://www.python.org/dev/peps/pep-0008/) unless an
+exception is listed below.
+
+See also the [Chromium OS Python Style
+Guidelines](https://sites.google.com/a/chromium.org/dev/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`](https://chromium.googlesource.com/chromium/src/+/master/styleguide/python/OWNERS)
+get to decide.
+
+[TOC]
+
+## 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.)
+
+## Tools
+
+### pylint
+[Depot tools](http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools.html)
+contains a local copy of pylint, appropriately configured.
+ * Directories need to opt into pylint presumbit checks via:
+   `input_api.canned_checks.RunPylint()`.
+
+### YAPF
+[YAPF](https://github.com/google/yapf) is a Python formatter that can be used via:
+
+```sh
+git cl format --python
+```
+
+Directories can opt into enforcing YAPF styling by adding `.style.yapf` file
+with the following contents:
+```
+[style]
+based_on_style = chromium
+```
+
+Entire files can be formatted (rather than just touched lines) via:
+```sh
+git cl format --python --full
+```
