What is the difference between py-evm and pythereum?

QUESTION

What is the difference between py-evm and pythereum?

Asked 2018-May-29 at 09:49

I usually use geth or parity client but trying to use pythereum for vyper implementation.

But looks like two types of ethereum clients using python implementation which are :

https://github.com/ethereum/pyethereum

https://github.com/ethereum/py-evm

Also, there is another python client called pyethapp too. (https://github.com/ethereum/pyethapp)

So can anybody teach me the differences and which situation should I use which?
