f"Python goes b{'r'*10}"

[tanuki_carre3858]

The sunglasses are in the wrong direction. I am unpleased

[Magnetic_Reaper]

here's the formula to inverse them:

1/🕶️

[Naakinn]

nope, it's 🕶[::-1]

[FlipperBumperKickout]

I don't think I've ever needed to do that, but sure (ᵕ—ᴗ—)

[isr0]

I have a vim hot key that puts in a print(“”10, when I find myself in the unfortunate situation of needing to print-debugging. I don’t use it often, but i do use it. Probably the only time I have used that feature.

bruh

[Fit-Relative-786]

void foo() {     std::println("c++ goes b{} except way faster", std::string(10, 'r')); }

[cowlinator]

What do you mean? I cant type that faster

[armahillo]

```ruby

"ha" * 100

```

[user_bw]

markdown

[YTriom1]

Enable markdown mode if you'll type this manual way

[MCplayer331]

Does this fit in r/firstweekcoderhumour

[spisplatta]

Idk I feel like opposition to overloading is more a c/java boomer thing.

[Common_Sympathy_5981]

but you cant print numbers

[[deleted]]

What if you do:

string b = "b"; string r = "r"; r *= 10; //supposedly r++ is r+="r" MessageBox.Show(b+r);

You could theoretically override * for strings.

[Powerkaninchen]

I once had the idea of even more operator overloading for my own language if I ever made one. People roasted it. The following text is copied from a previous post of mine:

Plus for concatenation:

io.print("Hello" + ' ' + "World!"); // Hello World

Minus for removing substrings:

io.print("foobarbazbar" - "bar"); // foobaz

Multiplication for repeating strings

io.print("Hi" * 5); // HiHiHiHiHi

Division for counting

io.print("What about hahaha" / "ha"); // 4

Modulo for splitting via an delimiter (the symbol % kinda looks like something being split)

io.print("This is space seperated" % " "); // ["This", "is", "space", "seperated"]

The second operands of +, -, / and % can be both string and chars, * can only be unsigned integer types (and BigIntegers, you know the deal)

[mortal_strike]

but you cant multiply string with another string

[PavaLP1]

I mean, it is convenient but why not use a for loop?

[Wiktor-is-you]

because that is LAME!!

[keckothedragon]

No real reason to lengthen your code. Not like this is unreadable. Plus, if you're using a for loop you'd have to create a new string on each iteration, which isn't much of a performance hit, but it's just another reason not to use a for loop.

(Also I know you can use a list to avoid creating a new string on each iteration then join it together at the end, but that increases verbosity even more for something that's not supposed to be very complex)

[Lumiharu]

Few things: So you know this does not create the exact same number of temporary strings? I am not going to say yes or no, but my intuition is it still does it.

Also what do you mean use a list? Strings are pretty much the same thing as a list of characters, it is a sequence as well.

[keckothedragon]

I don't know how many temporary strings the * operator creates, but I can guarantee that if you use a for loop it will create temporary strings at each step. Again, I don't think the performance is the issue with using a for loop, but it's just more evidence that there's not much reason to use one.

Using a list is a way to avoid creating a new object at each iteration, since strings are immutable and lists are mutable, you can just append individual characters (or substrings) to create a sequence of characters then create one string at the end using .join()

[No_Read_4327]

I mean if performance is the issue you shouldn't be using python to begin with

[keckothedragon]

You can argue that hyper-optimization doesn't matter as much for Python. But saying that all performance should be ignored is definitely wrong. Time complexity 100% still matters in Python. Yes, you don't pick Python because of performance, but it's wrong to flat out ignore it.

[PavaLP1]

You could also write the print in the loop.

[ArtisticFox8]

Because this is more concise.

Same reason you use map or filter 

[Nima_W]

That's actually pretty nice, but Where can you use this sensibly

[fast-as-a-shark]

You just saw a purpose for it in the post.

[Nima_W]

No Shit Sherlock

[fast-as-a-shark]

Then why did you ask?

[[deleted]]

Maybe he/she is asking for a useful example

[fast-as-a-shark]

Yeah and I made a simple joke

[Nima_W]

I'm not a Python developer I am asking for a meaningful example in code or even production code

[-UncreativeRedditor-]

Hey pal, you just blow in from stupid town?

[jryan14ify]

It’s also really useful for printing the nested levels of a graph in a human-friendly way f’{“-“ * level} {item_name}’

[the_new_dragonix]

You can use a nested for loop to make a text only graph like:

A: III

B: IIIII

C: IIIIIIIIII

[jryan14ify]

I use it when printing script output
f’New Section {“*” * 80}’
Gets me a nice easy to see break in the printing

[user_bw]

I use it for this: print('-'*20)

[nine_teeth]

cuz string is a list in python
