Hello,
Is there some sort of documentation where I can get all VPP methods avaible
for API purpose.
For example, he you used two methods - api.show_version and connect :
> r = vpp.connect('papi-example')
> rv = vpp.api.show_version()
How can I be able to take a outlook of what methods are avaiable in order to
build my own API?
Best Regards

I don't believe so. I use Python 3.8 on most systems.
