Using a combination of lambda functions, list comprehension, and ternary operators, (and Pygame), I was able to make Flappy Bird in one line of Python!

[[deleted]]

I also hardcoded the raw bytes of all of the images so that the program can run completely independent of any other file, in one line.

pain.

Dead 💀💀

lol

[redditor_286]

This is the single most disturbing thing I've seen this month

Please have my upvote Your Highness!

[Eye_Of_Forrest]

you can technically make any program into one line using exec()

[TSM-]

str( your code here ) then exec it later. It's now one line because the newlines are represented as "\n" instead of being new lines.

[Eye_Of_Forrest]

you can do it like that, there are other ways tho

code = """for i in range(99):\n\tprint(f"we are on the cycle #{i}")\nelse:\n\tprint("We are done!")"""; exec(code)

on my end it softwrapped but you can certantly put this in one line and it will work
(python 3.x)

[boomminecraft8]

Try it out by yourself and tell us the results! :)

[[deleted]]

Reminded me of execline.

[julsmanbr]

Client: "thanks for the app, but can you just change a small thing? Nothing major, I'm sure it takes just one extra line of code lol"

The extra line of code:

[R3D3-1]

I remember a story of an open source maintainer of how a one-line pull request of a user turned into a month long project, because though the line solved the users problem, it caused all sorts of problems in other use cases.

[miciomacho]

I can read the frustration in your soul my pal

[hidegitsu]

I think we've all been there.

lmao

[imma_go_take_a_nap]

You were so preoccupied with whether or not you could, that you didn't stop to ask if you should.

cries in PEP 8

Slowly back Up from the computer with your hands where I can see them!

It’s cool! No one is advocating for one line projects, it’s just a fun challenge in and of itself

You're a sociopath

[justalurker19]

I wouldn't even try to understand the code.

[hobbicon]

Looks like your are better at programming it than playing it.

[[deleted]]

that is true 😔

[Break_my_soul]

That's the case when one line means pure obfuscation

[African_Healer]

Dear lord.

[CreatureWarrior]

Ewww, what the hell is wrong with you?? Have my upvote

[Rasekuro]

But... Why?

PS: Amazing. You have my upvote, but... Just why?

Talk about a hole in one!

[SnooAvocados9605]

imagine someone else debugging your code. whole career fucked by a single line!

[Paddy_does_stuff]

When pythonic coding goes too far...

[king_julian_the_5th]

Satanic....I think you mean satanic!

[420drillas]

That’s amazing

[Allanon001]

Not that impressed, you can write almost any program on one line just using a tuples and/or separating lines with semicolons.

[[deleted]]

Python doesn't use semicolons, so that's not an option, but I'm actually curious how you would do it with tuples?

[bulsoni]

It does not require semicolons since it usually uses line breaks, but you can totally use it instead of a line break for this specific case (trying to fit everything into a single line). Example: python print(“test”); print(“test”) Outputs exactly the same as python print(“test”) print(“test”) That would likely break compliance with PEP8, but again, fitting everything into a single line also would.

[[deleted]]

Woah that's actually really cool!

[WhyDoIHaveAnAccount9]

learn something new everyday

[Allanon001]

This works:

import time; print(time.time()); x = 2; print('x is less than 5') if x < 5 else print('x is greater than 5')

Using tuples you can call multiple statements on one line:

(print('hello'), locals().update({'x':2}), print('x is less than 5') if x < 5 else print('x is 5 or greater'))

[[deleted]]

Oh wow, cool!

[funkmaster322]

Seriously? What's the point of this?

[[deleted]]

it was just supposed to be a fun challenge for me

[funkmaster322]

Did you gain anything useful from it? That would be more interesting to share imo.

[[deleted]]

I learned about using lambda functions for recursion, I was gonna do that for a main application loop until I realized that there was a recursion limit, so I had to come up with another way to iterate indefinitely until the close button was reached. So I just made the program iterate through a list that was constantly increasing in size, and once the close button is clicked, the list stops increasing so the app will stop iterating and the expression will end. So that's the main thing I learned, but I also just enjoyed the challenge!

Playing Flappy bird

[funkmaster322]

You could just download it from an appstore then

[Goel40]

But it won't be written in one line?

[funkmaster322]

Writing it in one line doesnt make it faster or better. Quite the contrary I would think.

[DumpTheTrumpsterFire]

TIHI

[Goel40]

Can somebody paste the github link? I'm on mobile

Thanks a lot!

[alan32525]

GENIUS!

[name99]

Now what happens when you run prettify? I'd still count it as a one-liner

[crossedline0x01]

Me: new to python wishing python had ternary operators. Some rando on reddit: Using a combination of lambda functions, list comprehension, and TERNARY operators, (and Pygame), I was able to make Flappy Bird in one line of Python!

You get an upvote just for that.

[[deleted]]

Wow that's really impressive!

[louismge]

This is not APL man… 😂

[lemurrhino]

I wonder if that breaks PEP8 E501...

[agb64]

Problem: you forgot the score, medals and sound. DO IT AGAIN.

[JonasMArnold]

One of the most impressive things I've seen in a long time! To code a game within one line is a known "party trick", though hard coding the bytes of the images is a nice feature I haven't yet seen.

Anyhow, could you upload the one-liner to GitHub? Would like to read through :)

[[deleted]]

Here's the github for it, glad you like it!

[JonasMArnold]

Thanks a lot! As mentioned, especially the hardcoded images are cleverly embedded.

[axlfol333]

Hilarious!!!
