fix: replace localhost with ip address in case localhost is ipv6 addr?? Norbert had an issue with his docker container where the healthcheck was timing out/failing. He diagnosed it as a ipv6 address bound to localhost. Not sure if this is the right fix. Might be better to determine where localhost is bound (V4 or V6 address) but I don't have an environment I can test with.

try:
    # Python 3+
    from http import client, server
except (ImportError, AttributeError):
    # Python 2.5-2.7
    import BaseHTTPServer as server  # noqa: F401
    import httplib as client  # noqa: F401
