Hanukkah famously has eight nights of celebration. The Hanukkah menorah, however, has nine candles:?eight regular candles and a ninth that is always offset. It is called the shamash?or shamos, which loosely translates to meaning "servant" or "janitor." The shamos is?the candle that lights all the others: it is the only candle whose fire can be used, not just watched. As we wrap up our series on the Zen of Python, I see how namespaces provide a similar service. read more

How to tell if implementing your Python code is a good idea

  • Opensource.com; By Moshe Zadka (Posted by bob on Dec 29, 2019 9:24 PM EDT)
  • Story Type: Roundups; Groups: Python
A language does not exist in the abstract. Every single language feature has to be implemented in code. It is easy to promise some features, but the implementation can get hairy. Hairy implementation means more potential for bugs, and, even worse, a maintenance burden for the ages. The Zen of Python has answers for this conundrum.

The Zen of Python: Why timing is everything

Python is always evolving. The Python community has an unending appetite for feature requests but also an unending bias toward the status quo.

The principle of least surprise is a guideline when designing user interfaces. It says that when the user performs an action, the program should do whatever would surprise the user the least.

Handling "exceptional conditions" is one of the most debated issues in programming. That could be because the stakes are high: mishandled error values can bring?down even the largest systems. Since "exception conditions," by nature, are the least tested but occur with unpleasant frequency, correctly handling them can often distinguish a system that horror stories are told about to a system that "just works." read more

Software development is a discipline rife with trade-offs. For every choice, there is an equally defensible but opposite choice. Make a method private? You're encouraging copy-paste. Make a method public? You're committing prematurely to an interface. Software developers make hard choices every minute. While all the principles in the Zen of Python cover trade-offs to some extent, the following principles take the hardest, coldest?look at some trade-offs.
