Re: [Python-ideas] Proposal: Query language extension to Python (PythonQL)

Hello, I've been following PythonQL with interest. I like the clever hack using Python encoding. It's definitely not something I would recommend to do for an inclusion in Python as it hijack the Python encoding method, which prevent your from... well choosing an encoding. And requires to have a

Re: [Python-ideas] Proposal: Query language extension to Python (PythonQL)

I think it's extraordinarily unlikely that a big change in Python syntax to support query syntax will ever happen. Moreover, I would oppose such a change myself. But just a change also really is not necessary. Pandas already abstracts all the things mentioned using only Python methods. It is

Re: [Python-ideas] Proposal: Query language extension to Python (PythonQL)

Hi Pavel, This is a really impressive body of work. I had looked at this project in the past but it is great to get back up to speed and see all the progress made. I use Python + databases almost every day, and the major unanswered question is what benefit does dedicated language syntax have

Re: [Python-ideas] Proposal: Query language extension to Python (PythonQL)

First off, I think PythonQL (and PonyORM before it) is a very interesting piece of technology. However, I think some of the answers so far suggest we may need to discuss a couple of meta-issues around target audiences and available technical options before continuing on. I'm quoting Gerald's post

Re: [Python-ideas] Proposal: Query language extension to Python (PythonQL)

Pavel, I like PythonQL. I perform a lot of data transformation, and often find Python's list comprehensions too limiting; leaving me wishing for LINQ-like language features. As an alternative to extending Python with PythonQL, Terry Reedy suggested interpreting a DSL string, and Pavel Velikhov
