> Add python example script
> Key: ZOOKEEPER-765
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-765
> Project: Zookeeper
> Issue Type: Improvement
> Components: contrib-bindings, documentation
> Reporter: Travis Crawford
> Assignee: Andrei Savu
> Priority: Minor
> Fix For: 3.4.0
> Attachments: zk.py, ZOOKEEPER-765.patch, ZOOKEEPER-765.patch
> When adding some zookeeper-based functionality to a python script I had to
> figure everything out without guidance, which while doable, would have been a
> lot easier with an example. I extracted a skeleton program structure out with
> hopes its useful to others (maybe add as an example in the source or wiki?).
> This script does an aget() and sets a watch, and hopefully illustrates what's
> going on, and where to plug in your application code that gets run when the
> znode changes.
> There are probably some bugs, which if we fix now and provide a well-reviewed
> example hopefully others will not run into the same mistakes.
