Addition of specific example of great code from one of the listed repositories.

I absolutely love the Reading Code section, and I've been going through some of the repositories and identifying specific examples of why the code is good.

I was hoping to add one such example to the page. Specifically, from howdoi. It's virtually at the top of the codebase and it deals with standardizing the repository for Python 2 and 3.

https://github.com/gleitz/howdoi/blob/master/howdoi/howdoi.py

# Handle imports for Python 2 and 3
if sys.version < '3':
    import codecs
    from urllib import quote as url_quote
    from urllib import getproxies

    # Handling Unicode: http://stackoverflow.com/a/6633040/305414
    def u(x):
        return codecs.unicode_escape_decode(x)[0]
else:
    from urllib.request import getproxies
    from urllib.parse import quote as url_quote

    def u(x):
        return x

I think that there are two (and a half) key pedagogical takeaways from this.

The half takeaway is that supporting different versions of Python need not be a grueling task.

The remaining two are -

1. Appropriate use of control flow for module imports and function creation
2. Standardizing an API so that its source is indistinguishable to the rest of the code and functionality is consistent.

I haven't formally written this up yet, but if you think it would be a useful example, I can do that and submit a pull request.

Reading Code セクションと、リンクされている howdoi/howdoi.py の例から始めてください。Issue に記載されている Python 2/3 の import 処理、制御フロー、一貫した API について正式な説明を作成し、適切なページに追加してください。例とその教育的な要点が pull request に含まれれば完了です。
