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: ) No matching distribution found for puffadder $ pip --version pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7) $ pip3 --version pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6) $ pip3 install puffadder==0.1 Collecting puffadder==0.1 Could not find a version that satisfies the requirement puffadder==0.1 (from versions: ) No matching distribution found for puffadder==0.1 $ pip install puffadder==0.1 Collecting puffadder==0.1 Could not find a version that satisfies the requirement puffadder==0.1 (from versions: ) No matching distribution found for puffadder==0.1 $ sudo lsb_release -a No LSB modules are available. 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?

Answer
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
