Python problems...
-
To be perfectly honest I think the retail price of Python has more to do with it popularity than anything else. Remember you get what you pay for. :omg:
Granted, the "price is right". Python is very handy for one-off kind of stuff. I am using it to debug/tune Chris's CP-AI used with Blue Iris, mostly BI settings. Watch for a change in the BI log, filter it with what I am looking for and send me an SMS. Handy to get a heads up so as to check out the event. Maybe trivial, but handy. Also use it from time to time as a syslog server when looking for people trying to access sites they don't belong on using the corp LAN. Cleanup after ransomware is no fun. Now, this payroll program I an writing with Python is more of a struggle. :) An intellectual is someone who can listen to the William Tell Overture and not think of the Lone Ranger. ¯\_(ツ)_/¯

I'm not talking about using the spacebar to indent code. I don't think the issue is about what key is pressed, but about what characters are produced and stored. Back when using a VT we had to indent by using the spacebar. But with modern(ish) IDEs we use the TAB key, and have it insert either SPACEs or TABs as configured -- the result looks the same, but it isn't. I don't recall what Turbo Pascal and C/C++ did with TABs. When I use Notepad, I still have to use the spacebar to indent because it uses eight-character-wide TAB-stops, but I don't use that for code.
Tab spaces should be in half-inches or centimeters, depending where you live. Not characters.
Nothing succeeds like a budgie without teeth. To err is human, to arr is pirate.

Worse: space and tab are not the same: so two lines which look to be identically indented in your chosen editor can be in different code blocks as a tab is one whitespace regardless of the visual effect. X|

Why don't Python editors indicate tabs/spaces with some sort of symbol? Perhaps '{' for tab and ' ' for space. To be even more helpful, the editor could indicate the end of a block with '}' ?

Hi All, Being strongly encouraged (read forced) to use Python for a test rig. Okay need to get down with Kids etc. but syntactic white space 'align your tabs' (who came up with that, is it 1988, am I using a BBC micro) oh gord!!!:mad:
Ok, so, I'm going to give you the single best use-case for bothering with Python. Jupyter Notebooks. It's a webserver-based environment to document, script, and generate results in a single document. You can transform notebooks into slides, so you can teach a class. You can effectively collab with people on notebooks, so you can do research across the globe. You can generate and plot all manner of graphs, so you can use it to prove something. There's markup and HTML support if you need it. Anything else --> don't use Python

"use tabs" to save file space
I'm quite certain that isn't the reasoning. I think some TABophiles use TABs to save keystrokes. I, of course, use two SPACEs per TAB and otherwise a whole :elephant:ing load of whitespace, vertical space in particular. I am not interested in "saving space" or "saving keystrokes" I need space so I can read the stuff. The simple IDE I developed for myself defaults to TABs because there is no reasonable number of SPACEs to use as a default instead. But what can save file space is that it right-trims SPACEs from lines when it saves a file -- that eliminates a lot more characters from saved files than using TABs.
I do not understand why anyone uses spaces tbh. I also set my tab spacing to 2, but most of the legacy code I work on - and even some of the newer stuff added to that legacy code - uses spaces, and are thus untidy along the left margin and often not collapsible. Use tabs, for the love of pretty code, and for that matter, used blank lines between logical blocks. And concise comments.

Finished the tutorial I had to do, I can say it gets around some problems (& creates it own) but there never issues I have had I mean 'you can create a web server in two lines', a good 90% of the code I have written is embedded (except a few test rig software front ends), by embedded I mean small memory, limited output and tends to be mounted in a hole under ground or under water. So web is not an issue...

I see no reason it wouldn't be collapsible. What IDE can't collapse it? How does your code look if you open it in another IDE/editor? Open it in Notepad for instance.

I agree, but only as an ideal as I know no IDE which can do that.

Let’s agree to disagree :) There is a reason however why letters have a certain height to width ratio. Also paragraph indenting, in books that use it, is proportional to font size. Your artistic eye might know better than your logical brain :)

True. However English text is the not the same as programming. I read English very fast and often deliberating skip parts. Certainly I am generally oblivious to periods. But ignoring a period in programming would be a bad idea. In the editor I use the typeface is specifically not proportional. I have tried it and found it to be a very bad idea. In English text the layout of the text seldom has meaning. In programming the layout does convey information such as easily seeing blocks.

I use spacing to provide formatting. Tabs in a file, not spaces allows one to skip backwards with fewer keystrokes. Never seen that happen with pseudo spaces (tabbing but with space replacement.) Since I am also very much a touch typist auto indenting tends to be a hinderance since it tends to break my train of thought. While tabbing (space replacement or not) is fewer keystrokes to get to where I actually want to be without it.

Yes, I can see that, but it isn't that big of a deal for me, in fact I think I frequently use the mouse to do that, which is worse. Also, when using two SPACEs per indent it's less of a burden than with four.

I definitely am not, but coding is like writing literature, so it's OK.

Unsure what you are referring to. If you mean having a new line auto-indented to the same level as the previous when you hit RETURN, I like that. With my coding format style, I have a lot of indent levels, so that saves me type.
jschell wrote:

There are still things Visual Studio does which I don't like and I seem to have no control over them, and I occasionally have to UNDO (Ctrl-Z) an auto-formatting change it made. It's part of why I wrote my own simple IDE which does only what I want it to.

Oh no ... 😊 this is not my cup of tea, I’ve seen one or 2 fragments on YT a few years ago, and I found it ridiculous, beyond strange, not really interesting ... Thus risible fits here also I guess, but why “wisible”? 😊 My intuition says that this is the pronunciation from the movie - is this guess correct?

Considering it was named after the people who gave us the Ministry of Silly Walks, Dead Parrots, and the Argument Sketch, what else would you expect?

Had to look that word up, which caused me to be risible.
I’ve given up trying to be calm. However, I am open to feeling slightly less agitated. I’m begging you for the benefit of everyone, don’t be STUPID.

I didn’t say the text of a program is the same as the text of a novel. What I do say however is that people writing programs could use a bit from the centuries of experience of typographers. It might be one of my (many) obsessions, but being somewhat dyslexic, I pay a lot of attention to things like font typeface, tab sizes page layout and such. When things go well, my programs are a thing of beauty in content and form. That happens rarely 🤪

Most editors can, but they tend to default to "use tabs" to save file space. And some only do it for modified lines, and ... it's a mess. Just don't use Python is my advice! :laugh:

I refer to it as "invisible source code" because that's what significant whitespace is. And it's just as stupid as it sounds. How do you debug that which you cannot see? It's risible.
To err is human. Fortune favors the monsters.

Casting a spell to make it visible? Using talcum powder? Asking a blind colleague to do it for you?
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

It is scripted so it's slower than .NET code. And the UI? :~
But it gives the correct answers when you have complex variables. Dot-net can't do that.
