All the code must follow PEP 8. You can use Flake8 to check for compliance. Flake8 is installed by default to all server environments, via MoPyTools.
Flake8 provides a Mercurial hook, to perform a code check on every commit or qrefresh. Here’s an example of Mercurial ~/.hgrc file:
[hooks]
commit = python:flake8.run.hg_hook
qrefresh = python:flake8.run.hg_hook
[flake8]
strict = 0
If strict option is set to 1, any warning will block the commit. When strict is set to 0, warnings are just displayed in the standard output.
Read these:
All internal strings in our server applications must use the unicode type unless stated otherwise.
Exceptions are:
When the str type is used, the utf-8 encoding must be used:
>>> uni = u'Café'
>>> uni
u'Caf\xe9'
>>> uni.encode('utf-8')
'Caf\xc3\xa9'
>>> print uni.encode('utf-8')
Café
>>> print uni
Café
