A solution to this somewhat more advanced Python programming problem would be to useatexit.register()instead. That way, when your program is finished executing (when exiting normally, that is), your registered
Although many programmers use the == operator for string comparison, it is actually one of the least desirable methods to employ, primarily because it doesn’t specify explicitly in the code which type of comparison is wanted. Rather, the preferred way to test for string equality in C# program...
(Note: This article is intended for a more advanced audience than Common Mistakes of Python Programmers, which is geared more toward those who are newer to the language.)Common Mistake #1: Misusing expressions as defaults for function argumentsPython allows you to specify that a fu...
and needed an “all hands on deck” approach to get the game to the level of quality we wanted before it went out the door. As a designer, I wasn’t as important an addition as the extra programmers and artists that were rolling onto the game, ...
rc uses the if not scripting constructs instead of vanilla else and provides the same for loop you use in the Bourne shell. Although rc has a weak typing discipline, it incorporates a powerful mechanism to manipulate variables. rc is reasonably lightweight, thus making it faster than many trad...
1. When to Use Python Lists and when to Use Tuples, Dictionaries or Sets The introduction seems pretty straightforward when you’re just reading it, but when you’re actually working on a small python script or a whole project, the choice for a list or some other sequence type might not...
1. text.capitalize(): capitalize a letter This Python function capitalizes the first letter of a string. Note that if this string is an entire sentence, it will not capitalize every word; just the first word. But if you wanted to capitalize a name, for instance, you could use text.capi...
You normally use a software timer to poll, or even place the function in loop(). But what if another function is blocking the loop() or setup().So your function might not be executed, and the result would be disastrous.You'd prefer to have your function called, no matter what ...
We just added two lines of code in the while loop. Everything else is from MX. (LED pin changes with different Nucleo boards). Well, it doesn't work. It failed on Nucleo-L432KC and Nucleo-L452RE. Both are L4 MCU so they use the same FW and library. It can't pass throug...
You see, the majority of programmers are not just "irrational" as we all are, but their reliance on reasoning doesn't even exceed the mean of the population, which means they barely use reasoning at all, it's pure gut feeling.
