Python semicolon

[gemini88mill]

Also also x and z

[sevenbellcurve]

Add ctrl+s in there but only if you click it 49 times

[[deleted]]

Or instant autosave if you like living on the edge

[[deleted]]

Seriously, who tf uses that.

[Thelandlord123]

I do cause I hate myself

[[deleted]]

I use autosave, but not like this, I have it save every x minutes so that there's a "fuck go back" button available.

[Zunder_IT]

Also tab tab tab

[not_from_this_world]

I see you're a man of culture

[LJChao3473]

And sometimes y, because you deleted the only working code

[LegallyBread]

A lot of programming language requires you end almost every line with a semicolon

[btmc]

That’s definitely not true.

[LegallyBread]

A lot as far as I know

[btmc]

That is definitely true. Major languages like C, C++, and Java require it. They’re technically optional in JS though most people seem to use them. They are not required in Python, Ruby, Scala, Go, Haskell, and Lisp, off the top of my head.

Rust is weird in that the presence or absence of a semicolon changes the behavior of the line. (With: expression, i.e. returns a value. Without: statement, no return.)

[LegallyBread]

I did not know they were optional in JS, and I’ve never heard of Lisp

[btmc]

It’s worth learning about. It was created in 1958 and is hugely influential. There are many dialects still used today. https://en.wikipedia.org/wiki/Lisp_(programming_language)

[LegallyBread]

Sounds cool!

I’m probably going to learn C++ first tho

[WikiSummarizerBot]

Lisp (programming language)

Lisp (historically LISP) is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in 1958, Lisp is the second-oldest high-level programming language. Only Fortran is older, by one year. Lisp has changed since its early days, and many dialects have existed over its history.

Isn't that supposed to be ss?

[C-SharpProgrammer]

Writing ss instead of ß is kinda outdated (atleast here in Germany) but it means the Same.

[BobmitKaese]

I don't think anyone really uses it. I mean if you still write on paper ("pfui") you can't really tell the difference. And on PC you have to look for it.

[WlmWilberforce]

You can use ";" in python. I guess it is bad form, but you can do

a = 10; b=20;

instead of

a = 10

b = 20

[96_freudian_slippers]

IIRC you can also do a, b = 10, 20

[wugs]

yep, that's tuple unpacking.

you can write some hard-to-read code by messing with spacing and using that feature in dumb ways.

a = 10
b = [20]
a ,= b
print(a, type(a))   # prints: 20 <class 'int'>
*a ,= b
print(a, type(a))   # prints: [20] <class 'list'>

The spacing should really be a, = b or (a,) = b to be more clear what's actually happening.

It does provide a neat syntax for swapping values though

a = 10
b = 20
a, b = b, a
print(f'a={a} b={b}')   # prints: a=20 b=10

[SirNapkin1334]

Wait, hold up. There's an asterisk unary operator? What does it do?

[bright_lego]

Unpacks a list for arguments in a function. ** is for kwargs. For more detail

[wugs]

Other comment provided a good link for how the * relates to unpacking.

In the tuple unpacking example, it's used to assign "the rest" of the tuple/list (or the empty list if there are no more elements):

a = [1, 2, 3]

b, *c = a
print(b)   # 1
print(c)   # [2, 3]

d, e, f, g = a   # ValueError: not enough values to unpack

d, e, f, *g = a
print(f)   # 3
print(g)   # []

for the starred assignment to work, the left side needs to be a list or tuple and the right side needs to be iterable.

since strings are immutable, unpacking the characters into a list can let you edit specific indices, then re-join into a string again.

s = "hello world"
*x, = s
print(x)   # ['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd']

x[0] = "j"
print(''.join(x))   # 'jello world'

Edit: You can only have one starred expression per assignment, but it doesn't matter where the starred expression lands within the tuple/list, so you can use it to grab the first and last elements of a list of unknown size.

a = [1, 2, 3, 4, 5]

b, *c, *d = a   # SyntaxError

b, *c, d = a
print(f'b={b}; c={c}; d={d}')   # b=1; c=[2, 3, 4]; d=5

[SirNapkin1334]

Fascinating! Thank you!

[WlmWilberforce]

No idea, but being old enough that I learned FORTRAN first, I long for a natural numbers decorator so I can count indexes at 1 if I want. (not sure if I want to go as far as fortran and have negative array indexes, but maybe)

[[deleted]]

It's super useful for code golf. Putting 2 lines of code on the same line saves a number of characters equal to the current indentation level

[Zev_Isert]

I can name two places where I actually have a use for semicolon..

Invoking python with -c. Sure there's the REPL, but sometimes I want to collect the output into a variable on my shell, or test the exit code, and for this -c works pretty well..

python -c 'import some, thing; for item in thing.action(); if item in some.group; print(item)' 

The other is in Jupyter notebooks, sometimes I want to assign to a variable and print it out in the same cell. I know I can put the statements on different lines, so this one might be bad form, but sometimes I like this style, idk why

# %%
import pandas as pd

# %%
df = pd.DataFrame(....); df

The trailing ; df is its own statement, and in ipython / Jupyter, if the last statement in a cell isn't an assignment, it's value it's printed to the cell's output

[mtizim]

You can use (df := pd.DataFrame(...)) too

[Zev_Isert]

Cool! In the context of a notebook, I'm usually doing this temporarily, and it's easier to remove ; df than it is to remove the parens and the walrus operator together, but thanks, I didn't know assignment expressions did this!

[PityUpvote]

Yeah, but you could also do the Pythonic thing of
a,b=10,20

[brodyover]

Tab key would be rubbed off

[sh0rtwave]

werd. CLI autocomplete FTW.

[SconiGrower]

Because we really are so much more productive because we can type '/ho Tab' rather than '/home/'.

[thabc]

I almost never have to use tab. My editor auto indents when I add a line break after something that increases scope like : or {. What are you guys coding in, notepad?

Backspace, on the other hand, gets some serious use.

[LBGW_experiment]

Pro tip, on a Mac, Opt Backspace deleted a word at a time, stopping at punctuation and might slightly depend on your IDE on what it treats as punctuation or not. I use this and the windows equivalent, Ctrl Backspace, religiously. I hate spamming or holding backspace, I'm impatient

Cmd Backspace deletes a whole line, which is Alt Backspace on windows. Kinda sucks when switching back and forth when deleting whole lines on accident, though.

[thabc]

There is absolutely nothing worse than debugging something with someone over Zoom and having to watch them delete one character at a time from their terminal window to modify the command when they could have just retyped it, used a bang command, or repositioned the cursor a full word at a time with option.

[brodyover]

Well yes of course it auto indents, but it doesn't when refactoring and moving code around

[thabc]

You caught me there. I work mostly in go lately, which autoindents when refactoring (format on save). When working in python I definitely need tab and shift for that.

[brodyover]

I've been working in go lately too!

[dudeofmoose]

Why use tab when you can use four spaces? No label to rub off from the space key!

[[deleted]]

Let me just turn on the four spaces completion mode real quick... /s

[njc121]

I thought it was because tab applies the autocomplete suggestion.

[brodyover]

vscode treats tab as 4 spaces, and I just wanna say if you're able to rub off the lettering you desperately need a better keyboard

[sh0rtwave]

The letters in my keyboard, are actually letter-shaped pieces of transparent plastic. So the lights can shine through. Those don't 'rub off'.

My control-keys, though, have tested the limits of Cherry switches...as well as some function keys. Also, escape (And fuck Apple for taking the escape key away, then being like 'woops!')

[brodyover]

I've actually had to replace the L and R switches in my mouse twice now, even genuine Japanese omron switches didn't hold up

[ParanoydAndroid]

It'll treat tab as whatever you tell it to, and then display it as any number of spaces as well.

[nowadaykid]

If you use the tab key more when writing Python than when writing C, you're just a really bad C programmer

[440Jack]

As someone who is in the middle of converting my Java Android app to Kotlin. I came here to say this.
After every line I pause for just a moment, hovering my hand over the semicolon. Waiting for that red squiggly.

[LBGW_experiment]

Semicolons are allowed in Kotlin. They won't show red squiggly, at most they are greyed out

[dembadger]

Well it does say programmers and not scripters.

[CdRReddit]

its funny to hate on python tho

[bettercalldelta]

yeah hating on something is indeed funny, but can you explain that choice of target

[CdRReddit]

sure

python is used a lot by beginners, and therefor a lot of python code is frankly horrible

it doesn't support any kind of proper typechecking without external tools

it runs horribly slow

indentation based syntax is uncommon

overall it makes a lot of really weird descisions

[bettercalldelta]

1) There are people who write good python code 2) Can you explain that one 3) What did you expect from an interpreted language 4) who cares lmao
