Here the .stdout attribute of the CompletedProcess object of ls is set to the input of the grep_process. It’s important that it’s set to input rather than stdin. This is because the .stdout attribute isn’t a file-like object. It’s a bytes object, so it can’t be used as an...
Python’s philosophy is built on top of the idea of well thought out best practices. Python is a dynamic language (did I already said that?) and as such, already implements, or makes it easy to implement, a number of popular design patterns with a few lines of code. Some design patter...
This is the time when I’m going back to what I said earlier. To survive, to get a strong following and clients who rely on it, your technology has to be unique, sturdy, safe and custom tailored to your customers’ needs. At this point, it won’t be possible to avoid integration w...
The Zen of Python points out that "explicit is better than implicit" for a reason: ambiguity and implicit knowledge that is not easily communicated code is easy to get wrong and leads to bugs. By forcing developers to explicitly separate out their binary data and textual data it leads to ...
You can do this, but as I said above, it will block the whole process and make things mysteriously slow, and you shouldn't. Instead, you need to give the sync code its own thread. Calling async code from sync code. Trying to even use await inside a synchronous function is a syntax ...
"We'd like to pretend that 'Fredrik' is a role, but even hundreds of volunteers couldn't possibly keep up. No, 'Fredrik' is the result of crossing an http server with a spam filter with an emacs whatsit and some other stuff besides." ...
I realize that getting an issue without exact steps to reproduce is unhelpful. However, I am more than willing to try out test builds or build a customer version to gather more details if I can get some guidance. I was able to easily build a custom version on Linux per the dev docs,...
“Proving that you can collaborate with others to solve problems is a vital aspect during the job interview process,” said Nurkin. “It’s one thing to be a solid programmer, it’s another thing if you’re a programmer that works well with others to solve big challenges.” ...
Which character you use to enclose your strings is up to you, although using the single quote character is very popular with the majority of Python programmers. That said, and above all else, your usage should be consistent. Be consistent in your use of string quote characters. If possible,...
That said, calculating FFT remains a computationally demanding task. So, if your animation ends up looking choppy, then try to reduce the number of frequency bands by decreasing the sliding window’s size. Now copy the entire source code from plot_oscilloscope.py and paste it into a new scri...
