Comment 14 for bug 1912844

fwiw; Open vSwitch do distribute Python client libraries [0], but they may be a bit complex for this simple use case. We do maintain a SimpleOVSDB interface [1] and there is an example of how it could be used to iterate over stuff [2]. Feel free to use, steal or whatever suits your needs :)
