NumPy 1.25.0rc1 released
by Charles R Harris May 30, 2023

May 30, 2023

Hi All, The NumPy 1.25.0 release continues the ongoing work to improve the handling and promotion of dtypes, increase the execution speed, and clarify the documentation. There has also been work to prepare for the future NumPy 2.0.0 release, resulting in a large number of new and expired deprecation. Highlights are: - Support for MUSL, there are now MUSL wheels. - Support the Fujitsu C/C++ compiler. - Object arrays are now supported in einsum - Support for inplace matrix multiplication (@=). We will release NumPy 1.26 on top of the 1.25 code when Python 12 reaches the rc stage. That is needed because distutils has been dropped by Python 12 and we will be switching to using meson for future builds. The next mainline release will be NumPy 2.0.0. We plan that the 2.0 series will still support downstream projects built against earlier versions of NumPy. The Python versions supported in this release are 3.9-3.11. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.25.0rc1/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.25.0rc1>. *Contributors* A total of 145 people contributed to this release.

[RELEASE] Python 3.12.0 beta 1 released.
by Thomas Wouters May 22, 2023

May 22, 2023

I'm pleased to announce the release of Python 3.12 beta 1 (and feature freeze for Python 3.12). https://www.python.org/downloads/release/python-3120b1/ This is a beta preview of Python 3.12 Python 3.12 is still in development. This release, 3.12.0b1, is the first of four planned beta release previews of 3.12. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage maintainers of third-party Python projects to test with 3.12 during the beta phase and report issues found to [the Python bug tracker (Issues · python/cpython · GitHub) as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (Monday, 2023-07-31). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.12.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.12 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. Major new features of the 3.12 series, compared to 3.11 Some of the new major new features and changes in Python 3.12 are: - New type annotation syntax for generic classes (PEP 695 <https://peps.python.org/pep-0695/>). - More flexible f-string parsing, allowing many things previously disallowed (PEP 701 <https://peps.python.org/pep-0701/>). - Even more improved error messages. More exceptions potentially caused by typos now make suggestions to the user. - Many large and small performance improvements (like PEP 709 <https://peps.python.org/pep-0709/>). - Support for the Linux perf profiler to report Python function names in traces. - The deprecated wstr and wstr_length members of the C implementation of unicode objects were removed, per PEP 623 <https://peps.python.org/pep-0623/>. - In the unittest module, a number of long deprecated methods and classes were removed. (They had been deprecated since Python 3.1 or 3.2). - The deprecated smtpd and distutils modules have been removed (see PEP 594 <https://peps.python.org/pep-0594/> and PEP 632 <https://peps.python.org/pep-0632/>. The setuptools package (installed by default in virtualenvs and many other places) continues to provide the distutils module. - A number of other old, broken and deprecated functions, classes and methods have been removed. - Invalid backslash escape sequences in strings now warn with SyntaxWarning instead of DeprecationWarning, making them more visible. (They will become syntax errors in the future.) - The internal representation of integers has changed in preparation for performance enhancements. (This should not affect most users as it is an internal detail, but it may cause problems for Cython-generated code.) - (Hey, fellow core developer, if a feature you find important is missing from this list, let Thomas know <thomas(a)python.org>.) For more details on the changes to Python 3.12, see What’s new in Python 3.12 <https://docs.python.org/dev/whatsnew/3.12.html>. The next pre-release of Python 3.12 will be 3.12.0b2, currently scheduled for 2023-05-29. More resources Online Documentation <https://docs.python.org/3.12/>. PEP 693 <https://www.python.org/dev/peps/pep-0693/>, the Python 3.12 Release Schedule. Report bugs via GitHub Issues <https://github.com/python/cpython/issues>. Help fund Python and its community <https://www.python.org/psf/donations/>. And now for something completely different As the first beta release marks the point at which we fork off the release branch from the main development branch, here’s a poem about forks in the road. Two roads diverged in a yellow wood, And sorry I could not travel both And be one traveler, long I stood And looked down one as far as I could To where it bent in the undergrowth; Then took the other, as just as fair, And having perhaps the better claim, Because it was grassy and wanted wear; Though as for that the passing there Had worn them really about the same, And both that morning equally lay In leaves, no step had trodden black. Oh, I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back. I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I — I took the one less traveled by, And that has made all the difference. *The Road Not Taken*, by Robert Frost. Enjoy the new release Thanks to all of the many volunteers who help make Python Development and these releases possible! Please consider supporting our efforts by volunteering yourself or through organization contributions to the Python Software Foundation. Your release team, Thomas Wouters Ned Deily Steve Dower -- Thomas Wouters <thomas(a)python.org>

pytest-when 1.0.3
by Artem Zhukov May 19, 2023

May 19, 2023

Hi all, happy to announce a better developer experience with pytest-when fixture. With pytest-mock you can define the complex mocking behavior via natural interface: ``` when(some_object, "attribute").called_with(1, 2).then_return("mocked") ``` In this case the some_object.attribute(1, 2) == "mocked". But if it will be called with any other arguments, it will return what it is suppose to return. Project GitHub: https://github.com/zhukovgreen/pytest-when zhukovgreen/pytest-when: Pytest plugin for more readable mocking github.com Support python>=3.8 and tested until 3.11 Small example from the docs: # class which we're going to mock in the test class Klass1: def some_method( self, arg1: str, arg2: int, *, kwarg1: str, kwarg2: str, ) -> str: return "Not mocked" def test_should_properly_patch_calls(when): when(Klass1, "some_method").called_with( "a", when.markers.any, kwarg1="b", kwarg2=when.markers.any, ).then_return("Mocked") assert ( Klass1().some_method( "a", 1, kwarg1="b", kwarg2="c", ) == "Mocked" ) assert ( Klass1().some_method( "not mocked param", 1, kwarg1="b", kwarg2="c", ) == "Not mocked" ) # if you need to patch a function def test_patch_a_function(when): when(example_module, "some_normal_function").called_with( "a", when.markers.any, kwarg1="b", kwarg2=when.markers.any, ).then_return("Mocked") assert ( example_module.some_normal_function( "a", 1, kwarg1="b", kwarg2="c", ) == "Mocked" ) assert ( example_module.some_normal_function( "not mocked param", 1, kwarg1="b", kwarg2="c", ) == "Not mocked" ) Thank you for any feedback -- zhukovgreen, Data Engineer @Paylocity https://github.com/zhukovgreen

[Release] skforecast 0.8.0
by Joaquín a r May 17, 2023

May 17, 2023

Hi all, I'm delighted to announce the latest release of *s**kforecast*! *Skforecast *is a Python library that eases using scikit-learn regressors as single and multi-step forecasters. It also works with any regressor compatible with the scikit-learn API (pipelines, CatBoost, LightGBM, XGBoost, Ranger...). Docs: https://skforecast.org/ Why use skforecast? The fields of statistics and machine learning have developed many excellent regression algorithms that can be useful for forecasting, but applying them effectively to time series analysis can still be a challenge. To address this issue, the skforecast library provides a comprehensive set of tools for training, validation and prediction in a variety of scenarios commonly encountered when working with time series. The library is built using the widely used scikit-learn API, making it easy to integrate into existing workflows. With skforecast, users have access to a wide range of functionalities such as feature engineering, model selection, hyperparameter tuning and many others. This allows users to focus on the essential aspects of their projects and leave the intricacies of time series analysis to skforecast. Happy forecasting! -- Joaquín Amat Rodrigo
