What is a the Python program you requested given the following:
Complete the below
def DNSServiceEnumerateDomains(flags, interfaceIndex=kDNSServiceInterfaceIndexAny, callBack=None):

    ''''Asynchronously enumerate domains available for browsing and
    registration.
    The enumeration MUST be cancelled by closing the returned
    DNSServiceRef when no more domains are to be found.
    flags:
    Possible values are:
    kDNSServiceFlagsBrowseDomains to enumerate domains
    recommended for browsing.
    kDNSServiceFlagsRegistrationDomains to enumerate domains
    recommended for registration.
    interfaceIndex:
    If non-zero, specifies the interface on which to look for
    domains.  Most applications will pass
    kDNSServiceInterfaceIndexAny (0) to enumerate domains on all
    interfaces.
    callBack:
    The function to be called when a domain is found or the call
    asynchronously fails.  Its signature should be
    callBack(sdRef, flags, interfaceIndex, errorCode, replyDomain).
    return value:
    A DNSServiceRef instance.
    Callback Parameters:
    sdRef:
    The DNSServiceRef returned by DNSServiceEnumerateDomains().
    flags:
    Possible values are:
    kDNSServiceFlagsMoreComing
    kDNSServiceFlagsAdd
    kDNSServiceFlagsDefault
    interfaceIndex:
    Specifies the interface on which the domain exists.
    errorCode:
    Will be kDNSServiceErr_NoError (0) on success, otherwise
    indicates the failure that occurred (in which case other
    parameters are undefined).
    replyDomain:
    The name of the domain.'
