Posted on Wed 11 April 2018 in Posts • Tagged with pythonTipOfTheDay, python

So I was reviewing a coworkers pull request today and saw something I hadn't seen in Python before. As it turns out you can have multiple if clauses on a list comprehension. For example:

>>> [v for v in range(50) if v % 2 == 0 if v > 10]  # all even numbers …

Posted on Wed 14 February 2018 in Posts • Tagged with pythonTipOfTheDay, logging, python

Oftentimes you just want to try out something related to logging in the REPL, or in a hacky script.  Wading through the docs on the logging module is this painful exercise in reading about handlers and formatters and other stuff you don't care about.

The simplest way to just get …

Posted on Mon 15 January 2018 in Posts • Tagged with codeRefactorOfTheDay, refactoring, quality, python

I'm currently doing the 30-Day Code Quality Challenge (https://www.codequalitychallenge.com), and today's exercise was an interesting one -- extract a compound conditional.

Much has been said about how Microsoft has changed in recent years, no longer the super closed-source monopolistic giant it once was.  Regardless of whether or not you believe the change is real or just at the surface, permanent or temporary, etc, there is definitely some interesting things that have …

Python Tip of the Day - subTest!

Posted on Sat 23 September 2017 in Posts • Tagged with pythonTipOfTheDay, testing, unittest, python

Coming from a jUnit background, one of the things I always missed with the vanilla Python unitttest library was parameterized tests.  Oftentimes when writing unit tests for a particular unit you find yourself writing effectively the same test over and over again, but with different inputs. Wouldn't it be nice …

Git bisect And Nose -- Or how to find out who to blame for breaking the build.

Posted on Fri 03 August 2012 in Posts • Tagged with git, nose, python, testing

How did I not ever discover git bisect before today? Git bisect allows you to identify a particular commit which breaks a build, even after development has continued past that commit. So for example, say you:

  • Commit some code which (unknowing to you) happens to break the build
  • You then …

Handy Python tip #1

Posted on Thu 07 June 2012 in Posts • Tagged with pythonTipOfTheDay, python

The other day I was adding the rich comparison methods (the ones for operator overloading) to a class I had defined. Like many Python programmers before me I wondered "why is it that if I define a method for equality, I still have to define a not-equal method?" and "if …
