→Miscellaneous: add guidelines on strings, highlight code, add hint on string logging
== Miscellaneous ==
* Use logging.debug('foo %r bar', x) instead of logging.debug('foo %r bar' % x). This is more robust and formatting only happens if we actually log something.
* When you catch an exception and want to log it, use logging.exception(), this will print the whole backtrace and exception information, which is very useful when debugging.
