No, he didn't. There is a logging.handlers module; it's just not imported by
importing logging.

OP: logging is a package and logging.handlers is one module in the package. Not
all of the modules in a package are imported by importing the top-level package.
os.path is a particularly weird case because it is just an alias to the
platform-specific path-handling module; os is not a package.
