파이썬 문자열에서 공백이 여러개 연속으로 있는 경우, 이를 제거하고 공백을 하나씩만 남기는 방법입니다. 예시를 보겠습니다.

# 중복되는 공백이 있는 문자열
x = "my     name    is John."

우선 문자열을 split() 함수로 단어별로 분리해서 리스트(list)를 만들 수 있습니다.

# 단어로 분리하여 리스트로 저장
x_list = x.split()
print(x_list)

['my', 'name', 'is', 'John.']

아래의 코드를 사용하면 리스트를 공백(' ')을 구분자로 하여 통합(join)할 수 있습니다.

x_joined = ' '.join(x_list)
print(x_joined)

my name is John.

위의 과정을 한줄로 통합하면 아래와 같습니다.

x_processed = ' '.join(x.split())
print(x_processed)

my name is John.

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/gentbg-will-continue-to-burn-steem-with-reduced-posting-frequency Hello, this is @joviansummer(witness: @jswit). GentBG project has been going on for a few month. For more information about this project, check the following posts: GentBG - a new experiment to burn STEEM GentBG - why bother to burn STEEM? I'm making some changes to GentBG project's configurations. Unfortunately, this project haven't gained enough traction, but considering that burning STEEM is necessary(because STEEM supply has no limit) I'm going to continue this project as long as possible. The problem is that AI technology is not cheap. So I'm planning to change configuration to reduce the number of images per week from 2 to 1. Also, I don't think I can guarantee that image will be available every week. There might be a week without image. The current batch of images will be exhausted on September 18th. Configur...

GentBG - why bother to burn STEEM?

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/gentbg-why-bother-to-burn-steem GentBG - a new experiment to burn STEEM Hello, this is @joviansummer(witness: @jswit). I'd like to briefly explain why I bothered to start @gentbg experiment. Unlike bitcoin, STEEM has no supply limit. As long as STEEM exists, newly minted STEEM will be added to total supply. If we can't maintain corresponding demand or reduce supply, downward pressure on STEEM price can be a big challenge. @gentbg project is an experiment to reduce STEEM supply by burning. @gentbg will burn liquid author reward and delegate SP reward to @jsup to get amplified upvotes. The main purpose is to create a perpetual STEEM burning loop. I added a bit of fun factor via AI-generated images, to incentivize giving upvotes to @gentbg's posts. If you have some spare voting power, you can contribute to burning STEEM by giving upvotes to @gentbg's posts. Initial run of this experiment wil...

jsup 2.1 - investor's relief (experiment on separation of investment and SNS)

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/jsup-2-1-investor-s-relief-experiment-on-separation-of-investment-and-sns Hello, this is @joviansummer(witness: @jswit). I'm starting a new experiment regarding my @jsup vote service. The purpose of this experiment is to separate STEEM investment and social interaction(posting/commenting). For many people, writing a post daily(literally 365 posts per year) is not easy. It's not fun, and mandatory daily post only written for self-voting delegation service tends to result in useless low-quality content. I hope this new function of @jsup will reduce those posts, and also make it a bit more easy to invest in STEEM without worrying about daily posting. I think pressure of daily posting significantly undermines Steem as SNS. It's not fun. This is how it works: From 11:45 PM to 11:50 PM every night(reference time zone is GMT+9), @jsup checks if eligible delegators wrote something and received daily v...
