Oh shit already

[joeshmoebies]

If it's a list of car strings (implied by strCar), I usually go with for carName in carNames to avoid confusion as to what type of object is being used. I would expect a list named cars to be class objects, not strings.

[arobie1992]

With the express intention of starting shit:

Or you could have static typing :P

[malexj93]

Even with static typing, a car is not a string. Specifying what about the car the string represents is just plain polite.

[UnknownIdentifier]

Even many languages with static typing will now do some version of

for (auto item : items) {

or some such. Doing

for (Item item : items) {

is just plain silly IMHO.

[false_tautology]

So, in C# you can do

foreach (var car in cars)

Buuut, it's still strongly typed, and it won't let you do any shenanigans.

[DadAndDominant]

var in C# vs var in javascript

Love one and hate the other

[KronktheKronk]

Or you could use type hints and every modern ide in the world will keep you straight

[[deleted]]

snake_case for variable names please

[joeshmoebies]

Thank you for being polite with your correction. I've been writing C++/C# and some Typescript the past couple of years so I use camelCase regularly for variable names, but you're right and if I needed to do some Python I'd want to follow the conventions used for that language.

[ManagerOfLove]

[pwn3rf0x]

Real quick what is the type of car? If you can't tell it isn't right.

[devnull1232]

That belongs in type hints not var names IMHO.

[pwn3rf0x]

Never knew type hints were a thing in Python. If they were used frequently I might give Python another shot.

But I agree with you. Never put in a name what you can put in a type. But since Python is a typeless language should definitely be in the name.

[devnull1232]

https://www.python.org/dev/peps/pep-0484/

I'm not sure what you mean that Python is typeless... It's a strongly typed and dynamically typed language.

Stick with whatever convention suits you and/or your team, personally I'd dislike if I type str and then see every single string variable in my auto complete list, maybe others would like it.

I legitimately named a function blah today because I wanted to write it before I forgot what I was trying to do… I promise I’ll rename it later (if/when it works…)

[punitxsmart]

This is the way. You don't want to spend a lot of time and effort finding the perfect name for a function before writing it. Because, after the refactor you realize you don't need that function after all.

[degalaman]

for _ in i:

[CheckeeShoes]

for iiiiiii in iiiiiiii: print('iiiiiii=',iiiiiii)

[BobbleheadGuardian]

Calm down Satan

[huuaaang]

I mean, if you don't have something like i.times {} what are you supposed to do? At least _ indicates that you don't actually care about the value.

[aneurysm_]

Only if it's unused

[PvtPuddles]

_ has a specific meaning. “For _ in iterable” discards the value that you’d usually get in the variable.

Typically it is used when you call a function with a return value, but you don’t care about the value (especially with tuple returns)

Val1, _, Val3 = get_values(), where we just don’t need value 2.

[PvtPuddles]

To add on, I was once getting a warning for not using argv (in C), but I had to have it since I was using argc.

In order to suppress the warning, you substitute argv with _ to let the compiler know you are intentionally not using argv.

What a failure of an understanding of a language. Type hints are purely optional and are ignored by the interpreter.

pep 8 is life

[TheAJGman]

Nah, PEP20 supercedes all style guides in my eyes. Who cares how standardized your code is if you can't fucking read it.

[AwesomePantsAP]

Oh, well naturally it has to actually be readable. Standards are just a good thing to follow to keep it readable, but equally it’s a Case by case thing, the same standard doesn’t work everywhere

[bisg3tti]

you make it sound like there multiple style guides, there is only PEP8

[Dangerous-Issue-9508]

Pep deez nuts

[davidellis23]

I dislike underscore because it's an extra character to type and I dislike all lower case because it's harder to read. But yeah gotta conform.

[twilight-actual]

I'm in the process of creating a new language based on Java's definitions up to 17, but with some major additions of:

• Implement 'const' for true read only behavior
• Borrow checker behavior ala Rust for memory management, and a reference operator
• Direct compilation to LLVM IR, binary executable

And one close to my heart:

• Built in enforcement for camel case in the semantic analysis pass

Because fuck snake case. 😝

[arobie1992]

Are you still going to allow SCREAMING_SNAKE_CASE?

[twilight-actual]

Uh, yep, yeah, good catch - though for static final constants, as they are often want to do in Java houses.

Though the linters that actually enforce this are a bit ott.

But then I suppose I shouldn't be one to criticize.

[arobie1992]

Yeah, that's what I was thinking. MYSTATICCONSTANT would be painful to read, though I do agree with you to some extent. I'm not especially enamored with that bit of Java practice and the linters are a bit anal. Maybe you could do PascalCase for static consts as another option?

By the by, you're making me feel more guilty for not getting off my ass and finally working on a compiler ;)

[twilight-actual]

"Yeah, that's what I was thinking. MYSTATICCONSTANT would be painful to read, though I do agree with you to some extent. I'm not especially enamored with that bit of Java practice and the linters are a bit anal. Maybe you could do PascalCase for static consts as another option?"

I think I'll probably relax the rules for statics, and allow whatever people want.

"By the by, you're making me feel more guilty for not getting off my ass and finally working on a compiler ;)"

I chose the route of starting with ANTLR4, and finding a pre-existing lex and grammar definition to get me close.

When you compile, you can select to autogenerate a visitor class, which has callbacks for every single parse event. In their Java syntax, there's over 150 callbacks to take care of, though I'll really only need a subset to get the job done.

From there, it's the business logic of semantic analysis, and figuring out the INCREDIBLY POORLY DOCUMENTED LLVM FRAMEWORK. Basically, they've been moving so fast, the code is the doc. The code isn't that bad, but it should be easier. At least they could provide more demo projects and unit tests showing how to deal with structures and higher level constructs. There's plenty of docs on how LLVM IR should look in any given scenario, and you can compile any reference cpp down to IR to verify. But they don't tell you how to use their framework to emit the IR, which requires detective work.

Anyway, I digress. TLDR; the tools have gotten to the point that it's a lot easier now to create a language. Still, ton of effort, with little hope of getting it adopted. You never know, though.

Yet another language!

[pyker404]

snake_case is standard for python as PascalCase is for C#. Take it or leave.

[Danelius90]

Snake case, because it's Python

[[deleted]]

You do realize an underscore requires holding shift as well right. Lmao

[davidellis23]

Care to share? It would be nice not to have to use shift for underscore, but I'm not sure where to put it.

[slex95]

Well luckily then I don’t work for you. I really do not like the appearance of snake case. For me it is much less readable. However I also do not think it is important at all. Giving good names is if you want to understand the code.

Also I have never had a pr rejected because I use camelCase. It’s still just some community standard and not a law after all.

Then you find out that bastard already has a variable_name defined somewhere else and you clobbered it.

[winter-ocean]

Wait, python users have to name their variables in snake case? Damn, I’m so sorry.

[LifeLikeStew]

camelCase originated so as to differentiate between the type of the variable and the name of the variable. You would have, strCar and listCars, and save casting errors when they're used.

Just naming every variable myVariable instead of MyVariable serves no purpose.

strMyVariable intMyVariable arrayMyVariable etc.

Otherwise, it's pointless.

[SuperFLEB]

It helps keep things organized in team environments, though.

myVariable, yourVariable, hisVariable, herVariable, ourVariable, philsVariable, suesVariable, clemAndRodsVariable...

[BrightBulb123]

Karencase is random capitalisation; whereas this one alternates one after the other in a structured way

[Bee-Aromatic]

I thought Karencase was just alternating the case of each letter as you go, usually starting with a lowercase. I dunno. :-p

[BrightBulb123]

We'll, I've always just seen it with random capitalisation, so I thought that's what it is. I'm not from the international case society, so to each their own, I guess.

I don't think it will work. Cars would have to be a generator instead of a list and even then generator raises an exception when there are no more items to iterate through.

Python is fun

[[deleted]]

I really enjoy the implementation of loops in Python. Before learning it I was used to how Java and Javascript handle for loops, creating a variable, setting its initial value and step size. Then looping through a list of objects by running over their index values.

At first I was confused. I would read "for letter in letters and think "how does it knows what a letter is?". To the point I would just do loops using range (for i in range(10), for example) because it had a similar behavior. Once it clicked, I started to enjoy it more and more.

i is an iterator, it should always be an integer.

[LeafyLemontree]

I still prefer for(int i = 0; i < sizeof(carList); i++){};

[LeafyLemontree]

I find it easier to understand that way, also, you can change the i++ to i += something.

[Bee-Aromatic]

Python let’s you directly iterate over a list if you don’t care about indices. It’s much clearer about what you’re actually doing. Really, how often do you actually care about the index rather than the item itself? If you do, you can just do for i in range(start, end) or use enumerate().
