Great! But how does join() manage to insert needed spase quantity? The question is about the case <pre class='brush: python'>backward_string_by_word('hello world') </pre>

str.split(' ') will treat group of whitespaces as empty strings separated by whitespaces. <pre class='brush: python'>'hello world'.split(' ') == ['hello', '', '', 'world'] </pre>

Got you, thanks a lot!

The mission is exactly about it. I wish I would know it before...

why are there 2 '' (are these called none-spaces), when there are 3 whitespaces between hello and world in the string?

igharok on March 18, 2022, 9:40 a.m.
Because the string is splitted by spaces like this: 'hello world' = 'hello' + ' ' + '' + ' ' + '' + ' ' + 'world'

Exactly! I am proud I found the same solution by myself))

I'm new here and I don't understand why it works like this when there is something else before the "for". Сan someone give me a link to a resource where I can read about this?

thank you

Perfect solution! I made a 20 line code because I didn't figure out how to deal with two or more spaces

nekomatagikko on Feb. 6, 2022, 3:22 a.m.
me too! I made a 15 line code　:'-D

Me too because mine did not split out the spaces. Python 3.9. Only the words. Using string.split() got ['hello', 'world'] needed nested loops to put in the spaces. Now I see needs to be string.split(" ") lesson learned

Great solution!

I have the same solution :)

wow... don't have much else to say besides that. Just... wow. One liner and done. Hats off, man. Dang...

Great! I didn't understand str.split() perfectly until saw this.

Great solution! Simple yet it solved the task.

olena.rudenko on Sept. 18, 2023, 8:53 a.m.
omg, this is genious! I did the split without an argument and it didn't work so I used re, but it was so easy to fix apparently!

tamagoyaki on Nov. 6, 2023, 4:06 a.m.
オー。「text.split(' ')」と「text.split()」は別の動作をするんだね。参考になった

tamagoyaki on Nov. 6, 2023, 4:06 a.m.
Oh. "text.split(' ')" and "text.split()" have different operations. it was helpful
