Everyone who's developed with Python knows that you can run scripts from the command line using:
python myscript.pyand run applications or modules using:
python -m mymoduleThis is all very straightforward, but how do you run Python scripts and applications directly from the command line WITHOUT using the Python command, like regular scripts and programs?

From the outside, it might look like becoming a professional of any kind is a straightforward, if expensive, process. Get a degree or similar qualification, get a suitable job and get lots of experience so you can progress. All very privileged and elitist, apparently.
If only it were that simple. But it's not.

Junior software engineers tend to use straightforward and basic development techniques; the sort of techniques you might find taught in books and on many courses. These work, but many of them tend to be inefficient and slow. With more experience comes an urge to make things better, and to mature as an engineer:

This is an error that turns up occasionally when you're developing code in Python. It started happening in some code I was working on recently, and all of the articles I found when I was looking for the cause said the same thing; that you're trying to assign something to a value that's None. Probably something with an index or key, like a list or dictionary.
This didn't seem to match what I saw in my system at the time, but after looking much more closely it was right, although not for obvious reasons.

What Is It?
Go is a statically-typed, general-purpose, compiled programming language. It also gets called "GoLang" because that was the original domain name for the language, but its real name it Go. It’s fairly easy to learn, so you can get started quickly. It’s also quite high level, so it’s easy to be productive with it.

One of the principles of software development is “Resource Allocation Is Initialization", or RAII. This is useful as it avoids uninitialized values in your code, because all values are initialized when they're declared. It's a great way of avoiding problems with uninitialized references, because there aren't any!
You might not know it as RAII, but there's always the feeling that when you declare something you should initialize it, if only to stop the code linter from complaining.
Like anything else though, it's easy to go too far with this. When the objects in your system take an appreciable amount of time to create, and you want a lot of them, you'll find your application slows to a crawl.
Lazy Evaluation can improve performance dramatically!
