Logging and verbosity

Pooch uses the logging module to print messages about downloads and processor execution.

Adjusting the logging level

Pooch will log events like downloading a new file, updating an existing one, or unpacking an archive by printing to the terminal. You can change how verbose these events are by getting the event logger from pooch and changing the logging level:

logger = pooch.get_logger()

Most of the events from Pooch are logged at the info level; this code says that you only care about warnings or errors, like inability to create the data cache. The event logger is a logging.Logger object, so you can use that class’s methods to handle logging events in more sophisticated ways if you wish.
