Webinar and training about pytest basics (German / Switzerland)

2020-08-11 Thread Florian Bruhin 
Hey,

(Back in June, I've sent a mail about a pytest workshop I'm giving in
September. I'm not sure if it made it through everywhere, as I accidentally
used a mail address which wasn't subscribed to the lists I was posting to.
Since I also have a second announcement to make, I'm taking the freedom to post
another "marketing" mail - after that, things will likely be silent for a while
from my side again!)

Webinar
---

On August 18th (next week, if you read this mail on the same day I'm writing
it), I'm giving a 1h webinar about pytest basics in German:
https://mylearning.ch/kurse/online-kurse/tech-webinar/

This is in collaboration with the Institute for Networked Solutions (INS) at a
local university (Hochschule Rapperswil / HSR), hence the webinar is in German.
If you'd be interested in something similar in English, please let me know - if
there's enough interest, I'll repeat it in English at a later point in time.

Training


On September 8th, I teach a full-day pytest training as part of the CH Open
"Workshoptage" in Rotkreuz, Switzerland:
https://workshoptage.ch/workshops/2020/pytest-test-driven-development-nicht-nur-fuer-python/

Of course COVID-19 is still a concern for the physical training - the organizer
allows to cancel your ticket (with a full refund) up to two weeks before the
training takes place and also closesly monitors the situation in Switzerland.

Would be delighted to see some of you there! :)
For the webinar, there should also be a recording available later.

Florian

[RELEASE] Python 3.9.0rc1 is now available

2020-08-11 Thread Łukasz Langa 
Python 3.9.0 is *almost* ready. This release, *3.9.0rc1*, is the penultimate 
release preview. You can get it here:

https://www.python.org/downloads/release/python-390rc1/
Entering the release candidate phase, only reviewed code changes which are 
clear bug fixes are allowed between this release candidate and the final 
release. The second candidate and the last planned release preview is currently 
planned for 2020-09-14.

Please keep in mind that this is a preview release and its use is *not* 
recommended for production environments.

Calls to action

Core developers: all eyes on the docs now

 * Are all *your* changes properly documented?
 * Did you notice *other* changes you know of to have insufficient 
documentation?
Community members

We *strongly encourage* maintainers of third-party Python projects to prepare 
their projects for 3.9 compatibility during this phase. As always, report any 
issues to the Python bug tracker .

Installer news

This is the first version of Python to default to the 64-bit installer on 
Windows. The installer now also actively disallows installation on Windows 7. 
Python 3.9 is incompatible with this unsupported version of Windows.

Major new features of the 3.9 series, compared to 3.8

Some of the new major new features and changes in Python 3.9 are:

 * PEP 584 , Union Operators in  
`dict`
 * PEP 585 , Type Hinting Generics 
In Standard Collections
 * PEP 593 , Flexible function and 
variable annotations
 * PEP 602 , Python adopts a stable 
annual release cadence
 * PEP 615 , Support for the IANA 
Time Zone Database in the Standard Library
 * PEP 616 , String methods to 
remove prefixes and suffixes
 * PEP 617 , New PEG parser for 
CPython
 * BPO 38379 , garbage collection does not 
block on resurrected objects;
 * BPO 38692 , os.pidfd_open added that 
allows process management without races and signals;
 * BPO 39926 , Unicode support updated to 
version 13.0.0;
 * BPO 1635741 , when Python is 
initialized multiple times in the same process, it does not leak memory anymore;
 * A number of Python builtins (range, tuple, set, frozenset, list, dict) are 
now sped up using PEP 590  vectorcall;
 * A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, 
_crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use 
multiphase initialization as defined by PEP 489 
;
 * A number of standard library modules (audioop, ast, grp, _hashlib, pwd, 
_posixsubprocess, random, select, struct, termios, zlib) are now using the 
stable ABI defined by PEP 384 .

Vulture 2.0

2020-08-11 Thread Jendrik Seipp 

Vulture - Find dead code


Vulture finds unused code in Python programs. This is useful for
cleaning up and finding errors in large code bases. If you run Vulture
on both your library and test suite you can find untested code.

Due to Python's dynamic nature, static code analyzers like Vulture are
likely to miss some dead code. Also, code that is only called
implicitly may be reported as unused. Nonetheless, Vulture can be a
very helpful tool for higher code quality.


Download

https://github.com/jendrikseipp/vulture
http://pypi.python.org/pypi/vulture


Features

* fast: uses static code analysis
* tested: tests itself and has complete test coverage
* complements pyflakes and has the same output syntax
* sorts unused classes and functions by size with ``--sort-by-size``
* supports Python Python 3.6+


News

* Parse `# type: ...` comments if on Python 3.8+ (jingw, #220).
* Bump minimum Python version to 3.6 (Jendrik Seipp, #218). The last
  Vulture release that supports Python 2.7 and Python 3.5 is version 1.6.
* Consider all files under `test` or `tests` directories test files
  (Jendrik Seipp).
* Ignore `logging.Logger.propagate` attribute (Jendrik Seipp).


Cheers
Jendrik
