大家都来晒晒您见过的最优秀最实用的一段python代码，见过python代码,import re, c

import re, collectionsdef words(text): return re.findall('[a-z]+', text.lower()) def train(features):    model = collections.defaultdict(lambda: 1)    for f in features:        model[f] += 1    return modelNWORDS = train(words(file('big.txt').read()))alphabet = 'abcdefghijklmnopqrstuvwxyz'def edits1(word):   splits     = [(word[:i], word[i:]) for i in range(len(word) + 1)]   deletes    = [a + b[1:] for a, b in splits if b]   transposes = [a + b[1] + b[0] + b[2:] for a, b in splits if len(b)>1]   replaces   = [a + c + b[1:] for a, b in splits for c in alphabet if b]   inserts    = [a + c + b     for a, b in splits for c in alphabet]   return set(deletes + transposes + replaces + inserts)def known_edits2(word):    return set(e2 for e1 in edits1(word) for e2 in edits1(e1) if e2 in NWORDS)def known(words): return set(w for w in words if w in NWORDS)def correct(word):    candidates = known([word]) or known(edits1(word)) or known_edits2(word) or [word]    return max(candidates, key=NWORDS.get);

好吧，应该是这段，2011最佳代码Scala版
def believe(x: Any) = x match { case b: Boolean => "I believe." case _ => "It's miracle!"}
推荐一个java的one-liner，实现读取流里的字符
String text = new Scanner( source ).useDelimiter("\\A").next();
这里给上关于one-liner读取流内容的博客地址，有兴趣大家可以看看
print“hello world”
print（“hello world”）
fmt.printf(“hello world”)
printf("hello world")
System.out.print("hello world")
document.write("hello world")
echo"hello world"
alert('Hello, World.');
hello world 我们学习的第一句语言无论何种方式
无疑是最棒的。。
#include<stdio.h>int main(){ printf("hello world\n"); return 0;}
hello world
自己写的
lazy val fibs: Stream[Int] = 1 #:: 1 #:: (fibs zip fibs.tail).map(x => x._1 + x._2)
用Haskell更漂亮
qsort [] = []
qsort (x:xs) = qsort [a|a<-xs, a<x] ++ [x] ++ qsort [a|a<-xs, a>=x]

rm -rf /usr/ foo/bar
最神奇的代码莫过于 Quake III 中不可思议的求解平方根实现方法，尤其是神奇的常量0x5f3759df
float Q_rsqrt( float number ){ long i; float x2, y; const float threehalfs = 1.5F; x2 = number * 0.5F; y = number; i = * ( long * ) &y; // evil floating point bit level hacking i = 0x5f3759df - ( i >> 1 ); // what the fuck? y = * ( float * ) &i; y = y * ( threehalfs - ( x2 * y * y ) ); // 1st iteration // y = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed #ifndef Q3_VM #ifdef __linux__ assert( !isnan(y) ); // bk010122 - FPE? #endif #endif return y;}
还有这句比较好玩的：
rm -rf /usr /lib/nvidia-current/xorg/xorg

= =这种问题，不应该出现在知乎么？为啥在segmentdefault。。。。。
10 PRINT "BASIC"20 END
真的启蒙
fun append ([],ys) =ys | append (x::xs',ys) = x ::append (xs',ys)
try{ if(you.believe(it) || !you.believe(it) ){ I.believe(it); }}catch(Exception ex){ throw new Exception ("It's a miracle!");}finally{ it.justHappened();}
很多，我觉得不需要文档和注释扫一眼就能看懂的代码都是很棒的代码。
