I like this one

do you teach. you made than very logical and understandable. thank you

good ol ternery operator man. I always feel a sense of "oh yea i could of just done that" everytime i write an if/else statement, than come here to see others solutions.

I'm going to be very blunt because I'm growing very sick of comments like these. If this solution is bad practice or hardcore to you, then you shouldn't be doing Python. Plain and simple. There are many scenarios where one liners are bad, and this is not one of them. Under most style guides, this is the way to solve this problem. This is how it is done in production. Your solution has poor performance and looks like spaghetti - the gall to try and knock on the doors of better solutions talking about "not smart, but abstruse and overcomplicated." It is not the job of others to use simple language constructs to appease you. Look inwards and try to explore the language better.

Some people like to write one-liners as a challenge, not everyone is setting out to write perfectly readable enterprise-level code. It's not their fault other people upvote them. Let people have their fun without the lecture.

Not to mention, as far as python goes, this really isn't unreadable, it's pretty clear what this does.

Buddy, what is the overcomplication of this solution? Everything is simple and clear

you don't have nothing to do, this is look like a syndrome.

no it works for all kinds of words. the reason it works is calling split(' ') on strings with double or arbitrarily spaced characters produced empty strings in the return value, and when you call .join() all the empty strings are joined back with spaces between them. the empty strings from splitting multi-spaced strings act as placeholders for when the string is re-formed so the spacing is preserved

interesting

Writing everything in one line is a bad practice. It's just bragging about its tricky hardcore solution. It's too bad that many people called this solution "best practice" and "clever". This is a bad practice. And the solution is not smart, but abstruse and overcomplicated.

The solution from fortlasagna is much better. He generally does the same thing. But his code is much better structured and much better readable. Here he really shows the best practice.

mine is better

I missed the "All spaces in the string should be retained" part!
Other than that I got it! Wohoo!

That's clever for sure!

wow😂😍
