The idea with that snippet is to fail gracefully if the module isn't installed, either displaying a user-readable error (please install library-name to use this module) or, if reasonable, fall back to some other functionality. You'll notice further down, that the Netconf class (but not the Cli class) has the following snippet
if not HAS_JXMLEASE: > raise NetworkError( > msg='jxmlease is required but does not appear to be installed.

This is only for Netconf, as Cli does not depend on jxmlease, and therefore should not be gated by that lib.
