Add your name and email to our friends of the show list, we'll never share it. Michael #1: Vendorize packages from PyPI Allows pure-Python dependencies to be vendorized: that is, the Python source of the dependency is copied into your own package.Best used for small, pure-Python dependencies Brian #2: A Guide to Python's Weak References Using weakref Module Martin HeinzVery cool discussion of weakrefQuick garbage collection intro, and how references and weak references are used.Using weak references to build data structures. Example of two kinds of treesImplementing the Observer patternHow logging and OrderedDict use weak references Michael #3: Making Time Speak by Prayson, a former guest and friend of the showTranslating time into human-friendly spoken expressionsExample: clock("11:15") # 'quarter past eleven' Features Convert time into spoken expressions in various languages.Easy-to-use API with a simple and intuitive design.Pure Python implementation with no external dependencies.Extensible architecture for adding support for additional languages using the plugin design pattern. Brian #4: How Should You Test Your Machine Learning Project? A Beginner’s Guide François PorcherUsing pytest and pytest-cov for testing machine learning projectsLots of pieces can and should be tested just as normal functions. Example of testing a clean_text(text: str) -> str functionTest larger chunks with canned input and expected output. Example test_tokenize_text()Using fixtures for larger reusable components in testing Example fixture: bert_tokenizer() with pretrained dataChecking coverage Extras Michael: Twilio Authy Hack Google Authenticator is the only option? Really?Bitwarden to the rescueRequires (?) an update to their app, whose release notes (v26.1.0) only say “Bug fixes”Introducing Docs in Proton Drive This is what I called on Mozilla to do in “Unsolicited Advice for Mozilla and Firefox” But Proton got there firstEarly bird ending for Code in a Castle course Joke: I Lied

    Topics covered in this episode: Joining Strings in Python: A "Huh" Moment10 hard-to-swallow truths they won't tell you about software engineer jobMy thoughts on Python in ExcelExtra, extra, extraExtrasJokeWatch on YouTube About the show Sponsored by ScoutAPM: pythonbytes.fm/scout Connect with the hosts Michael: @mkennedy@fosstodon.orgBrian: @brianokken@fosstodon.orgShow: @pythonbytes@fosstodon.org Join us on YouTube at pythonbytes.fm/live to be part of the audience.

Brian #1: Joining Strings in Python: A "Huh" Moment Veronica Berglyd OlsenStandard solution to “read lines from a file, do some filtering, create a multiline string”: f = open("input_file.txt") filtered_text = "\n".join(x for x in f if not x.startswith("#")) This uses a generator, file reading, and passes the generator to join.Another approach is to add brackets and pass that generator to a list comprehension: f = open("input_file.txt") filtered_text = "\n".join([x for x in f if not x.startswith("#")]) At first glance, this seems to just be extra typing, but it’s actually faster by 16% on CPython due to the implementation of .join() doing 2 passes on input if passed a generator. From Trey Hunner: “I do know that it’s not possible to do 2 passes over a generator (since it’d be exhausted after the first pass) so from my understanding, the generator version requires an extra step of storing all the items in a list first.” Michael #2: 10 hard-to-swallow truths they won't tell you about software engineer job College will not prepare you for the jobYou will rarely get greenfield projectsNobody gives a BLANK about your clean codeYou will sometimes work with incompetent peopleGet used to being in meetings for hoursThey will ask you for estimates a lot of timesBugs will be your arch-enemy for lifeUncertainty will be your toxic friendIt will be almost impossible to disconnect from your jobYou will profit more from good soft skills than from good technical skills Brian #3: My thoughts on Python in Excel Felix ZumsteinInteresting take on one person’s experience with trying Python in Excel.“We wanted an alternative to VBA, but got an alternative to the Excel formula language”“Python runs in the cloud on Azure Container Instances and not inside Excel.”“DataFrames are great, but so are NumPy arrays and lists.”… lots of other interesting takaways.
