one-line tree in python

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

Basic steps for hosting on Github

Hey there, apparently people are still using this Gist from 2013! It's out of date! Consult the Github docs.

Steps for Hosting a Website on GitHub

  1. Create a GitHub account on github.com.
  2. Download either [GitHub for Mac][1] or [GitHub for Windows][2], depending on your operating system. Open the app and log in using the account you just created.
  3. (On Mac): After you login, click advanced and make sure that your name and email are correct. Then, click "Install Command Line Tools", just in case you want to start using the command line later in life.
  4. Create a new repository in your GitHub application. Name it your-username.github.io. The name is very important. Note the folder that GitHub is saving the repository to. Make sure the "Push to GitHub?" box is checked.
  5. Move your website's files into the folder that GitHub just created when you made the repository. IMPORTANT: Your homepage HTML file must be called "index.html", and it must exist in the top-level

왜 파이썬 데코레이터를 만들때, @wraps어노테이션을 쓰는 것을 권장하는 걸까?

왜 파이썬 데코레이터를 만들때, @wraps어노테이션을 쓰는 것을 권장하는 걸까?
이유인 즉슨, 데코레이터 내부에서 인자로 전달받은 함수가 익명함수 처럼 취급되어 버리므로 디버깅이 난해해지는 단점이 있었기 때문이다.
자세한 설명은 아래의 링크에 첨부되어 있다.

JS hoisting by example

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting

(I may be using incorrect terms below, please forgive me)

마크다운(Markdown) 사용법

[공통] 마크다운 markdown 작성법

영어지만, 조금 더 상세하게 마크다운 사용법을 안내하고 있는
"Markdown Guide (https://www.markdownguide.org/)" 를 보시는 것을 추천합니다. ^^

아, 그리고 마크다운만으로 표현이 부족하다고 느끼신다면, HTML 태그를 활용하시는 것도 좋습니다.

GitHub Gist 소개

GitHub Gist 소개

GitHub Gist는 GitHub과는 달리, private도 무료입니다. 저는 주로 코드조각(Code Snippet), 로그, 메모 등을 남기는데 사용합니다.
