• 结构模式匹配在 Python 3.10
  • BEN HOYT

“Python 3.10, which is due out in early October 2021, will include a large new language feature called structural pattern matching. This article is a critical but (hopefully) informative presentation of the feature, with examples based on real-world code.”

• 编程语言/ Python 正向前迈出了另一大步
  • LIAM TUNG

Python could soon take first place in one more programming language popularity ranking: “Python has never been so close to the number 1 position of the TIOBE index,” writes Paul Jansen, chief of Tiobe software. “It only needs to bridge 0.16% to surpass C. This might happen any time now. If Python becomes number 1, a new milestone has been reached in the TIOBE index. Only 2 other languages have ever been leading the pack so far, i.e. C and Java.”

超越 JAVA/C++ 的唯一方式就是变成它们

@with_goto
def range(start, stop):
    i = start
    result = []

    label .begin
    if i == stop:
        goto .end

    result.append(i)
    i += 1
    goto .begin

不觉中蟒周刊快译已经到了第9个年头

去年开始有小伙伴加入承担 pythonisa 周刊的翻译, 从来没提醒过, 可就这么默默坚持下来了...

问为什么:

[皱眉]每周新闻资讯 怎么能错过 
看看有什么新东西 
当有新的发现时：
    what f**k 还能这样玩？ 还有这东西？
    每周开彩蛋[吃瓜]

无法同意更多... 很多社区贡献看起来辛苦, 其实受益最多的, 就是主动承担者也.
