Does this output to the terminal? If so, what's the difference between this and print - if it is just the log level, how does it show that in the terminal?

A few points:

• logs are structured messages that follow an open standard (see Syslog)
• part of a log message's structure is its severity (INFO, WARN, ERROR, etc.)
• we should never use print in production servers as it will not interface with log explorers. We will be unable to filter log messages by their different dimensions. For example, we won't be able to filter to show all ERROR logs. This is critical!
• where the logs get sent to (console or other), can be configured with Python's logging handlers. Notice that I have defaulted Django's logging to print to console (StreamHandler prints to stdout a.k.a. console).
