puffadder (Lombok's alternative for Python) not maintained?

I am looking for some Python library similar to Java's Lombok. I found puffadder 0.1, from 2016, but now that I tried to install it with pip, it does not work.

Links:

• https://pypi.org/project/puffadder/
• https://libraries.io/pypi/puffadder
• https://github.com/IgniparousTempest/puffadder

Shell output:

$ pip3 install puffadder
Collecting puffadder
  Could not find a version that satisfies the requirement puffadder (from versions: )

$ pip --version
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

$ pip3 --version

$ pip3 install puffadder==0.1

$ pip install puffadder==0.1

$ sudo lsb_release -a

Distributor ID: Ubuntu
Description:    Ubuntu 18.04.3 LTS
Release:    18.04
Codename:   bionic

So, is it not compatible anymore with modern versions of Python? Why is not in pip anymore, was it discontinued, or just lack of integration in pip (so, I could maybe clone it from GitHub).

Also, does someone know some supported alternative, apart from using @property?

Python 3.7 added dataclasses Which reminds me of the Lombok in Java. It generates _init_, _repr_ and some more.

from dataclasses import dataclass

@dataclass()
class Name:
    first_name: str
    last_name: str

yoni = Name("Yoni", "Alaluf")
yoni2 = Name("Jony", "Alaluf")
print(yoni) # Name(first_name='Yoni', last_name='Alaluf')
print(yoni2) # Name(first_name='Jony', last_name='Alaluf')
print(yoni == yoni2) # False
