Heroku receives everything that your app sends to standard output (also
known as stdout), so the key question is how to send Python logs to
standard out.
Depending on the framework(s) you're using, here's 2 ways to do that:
* A very short way to force `logging` to use sys.stdout:
https://coderwall.com/p/_fg97w/creating-a-python-logger-to-stdout
* A more elegant/idiomatic way to use a stdout-backed `logging`
handler:
http://help.papertrailapp.com/kb/configuration/configuring-centralized-logging-from-python-apps/#logging-via-the-heroku-add-on
Note that, if you're calling `logging.warning` (instead of, say,
`logging.error`), you'll also need to set the level to at least
`warning` (or to a more verbose level like `info` or `debug`). The
examples above show how to specify the level at instantiation.
