(Copying from another response:)
I know this lib, "problem" is, that you still have to handle NetworkManager with
some strings, dictionaries etc. I would like to do it more Pythonic way, like:

add_bond(name, slaves), or even better with some context managers and stuff.

I would love to use D-Bus API, but I don't know what strings should I use for for
example adding bond and stuff like that. Thanks for links, but I think, i read them all.

Improving python-networkmanager could be fine, but i would like to do more
higher interface, as I mentioned in response to Yegor. Something like
Python nmcli.
