ANN: Lea 3.0.0 beta 2
by Pierre Denis May 27, 2018

May 27, 2018

Lea 3.0.0.beta.2 is now released! ---> http://pypi.org/project/lea/3.0.0.beta.2 What is Lea? ------------ Lea is a Python module aiming at working with discrete probability distributions in an intuitive way. It allows you modeling a broad range of random phenomena: gambling, weather, finance, etc. More generally, Lea may be used for any finite set of discrete values having known probability: numbers, booleans, date/times, symbols, . Each probability distribution is modeled as a plain object, which can be named, displayed, queried or processed to produce new probability distributions. Lea also provides advanced functions and Probabilistic Programming (PP) features; these include conditional probabilities, Bayesian networks, joint probability distributions, Markov chains and symbolic computation. Lea can be used for AI, machine learning, education, ... What's new in Lea 3? -------------------- Compared to latest version (2.3.5), many things have changed to extend the usability and openness of the library. To name a few: * ability to choose between different probability representations: floats, fractions and decimals * symbolic computation: Lea can now calculate probability *formula* using the SymPy library (http://www.sympy.org) * simpler API and compliance with PEP8 naming convention * revamped tutorials and examples -> http://bitbucket.org/piedenis/lea/wiki/Home Here is a short sample. A biased coins is flipped with 1/4 chance to be 'head'. Suppose that this coin is thrown 6 times. What is the probability to get no more than two 'heads'? Here is how you could make this calculation in Lea, using successively float, fraction and symbolic representations: print (P(lea.binom(6,1/4) <= 2)) # -> 0.83056640625 print (P(lea.binom(6,'1/4') <= 2)) # -> 1701/2048 print (P(lea.binom(6,'p') <= 2)) # -> (p - 1)**4*(10*p**2 + 4*p + 1)) print (P(lea.binom(6,'p') <= 2).subs('p',1/4)) # -> 0.830566406250000 To learn more... ---------------- Lea project page -> http://bitbucket.org/piedenis/lea Documentation -> http://bitbucket.org/piedenis/lea/wiki/Home Lea 3 on PyPI -> http://pypi.org/project/lea/3.0.0.beta.1 With the hope that Lea can make the Universe less uncertain, Pierre Denis

EuroPython 2018: Talk voting is open
by M.-A. Lemburg May 25, 2018

May 25, 2018

At EuroPython, we let our attendees have a significant say in the selection of the sessions which are presented at the conference. We call this “talk voting” - attendees can tell us which submitted talks they’d like to see at the conference. To be eligible to vote for talks, you need to be a submitter of talks and everyone who attended one of the previous year’s EuroPython conferences. Since we’re a bit short on time, talk voting will only be possible for a few days, until Sunday, May 27. How talk voting works --------------------- Please log in and proceed to the page https://ep2018.europython.eu/en/speakers/talk-voting/ to vote for talks. The talk voting page lists all submitted proposals, including talks, trainings and posters. At the top of the page you find a few filters you can use to narrow down the list by e.g. selecting tags you’re interested in or only show one type of proposal and also to select the sorting order. For each submission, you can find the talk title with a link to the talk page. In order to vote, have a look at the title/abstract and then indicate your personal interest in attending this session. We have simplified the voting process and you may chose between these four options: “must see”, “want to see”, “maybe” and “not interested”. Please ignore the option “not voted” - it’s an alias for “not interested”. If you have questions about the talk, you can go to the talk page and enter a comment. Note that your votes are automatically saved to the backend without the need to click on a save or submit button. Talk selection -------------- After the talk voting phase, the EuroPython Program Workgroup (WG) will use the votes to select the talks and build a schedule. The majority of the talks will be chosen based on the talk voting results. Part of the available slots will be directly assigned by the Program WG based on editorial criteria to e.g. increase diversity or give a chance to less mainstream topics. In general, the Program WG will try to give as many speakers a chance to talk as possible. If speakers have submitted multiple talks, the one with the highest rate will most likely get selected. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !

May 19, 2018

We would like to remind you that our two week call for proposals (CFP) closes on Sunday, May 20. If you’d like to submit a talk, please see our CFP announcement for details: https://blog.europython.eu/post/173666124852/europython-2018-call-for-propo… Submissions are possibe via the CFP page on the EuroPython 2018 website: https://ep2018.europython.eu/en/call-for-proposals/ We’d like to invite everyone to submit proposals for talks, trainings, panels, etc. Looking at the submission counts, we are especially looking for more trainings submissions (note that you get a free conference ticket and training pass as trainer of a selected training). Submissions will then go into a talk voting phase where EuroPython attendees of previous years can vote on the submissions. The program work group will then use these votes as basis for the final talk selection and scheduling. We expect to have the schedule available by end of May.

pytypes 1.0 beta 4 released
by Stefan Richthofer May 16, 2018

May 16, 2018

pytypes 1.0 beta 4 has been released. https://github.com/Stewori/pytypes Beneath several bugfixes, the most notable new feature is a utility function for explicitly resolving forward references, e.g. of a manually defined type. Another significant improvement is proper support for tuple ellipses. The converter utility stubfile_2_converter, alias typestubs, was improved significantly. It can now be used to dump type info from a module (or other stubfile) into a stubfile, supporting type comments and ordinary type annotations as input or output. E.g. it can convert type comments from Python 2 code to an original Python 3 style stubfile and vice versa. pytypes is a toolbox for PEP-484 style typing, explicitly supporting Python >= 3.3, Python 2.7, Jython >= 2.7.1, PyPy 3. Its main features include: - Runtime typechecking - Auto-annotating code from runtime observations in form of stubfiles - Utility functions: * PEP 484 aware subtype and instance checking: is_of_type(obj, tp) and is_subtype(subtype, supertype) * get_type_hints that takes stubfiles and type comments into account - Typesafe method overriding - Pull type information from stubfiles or type comments into __annotations__ for use by other tools - all features smoothly work with OOP, i.e. methods, static methods, class methods, properties pytypes is still in beta phase. File issues as the occur. Help is welcome! Github: https://github.com/Stewori/pytypes/releases PyPI: https://pypi.python.org/pypi/pytypes License: Apache 2.0 Enjoy! -Stefan
