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.
