按照提示改了下，好简洁。。。自己造轮子写的真丑。。。

这侧输出的好看多了：
i hope you didnt translate it by hand.
thats what computers are for. doing it in by hand
is inefficient and that‘s why this text is so long.
using string.maketrans() is recommended. now apply on the url.

从提示可知道，查看源代码，找到一段注释
<!--
find rare characters in the mess below:
-->
<!--
%%$@_$^__#)^)&!_+]!*@&^}@[@%]()%+$&[(_@%+%$*^@$^!+]!&_#)_*}{}}!}_]$[%}@[{_@#_^{*
@##&{#&{&)*%(]{{([*}@[@&]+
……
-->
#!/usr/bin/env python # coding: utf-8 # author: toddlerya # date: 2015-1-27 # 把那一段注释里的内容 放到rare_char里面 rare_char = """ %%$@_$^__#)^)&!_+]!*@&^}@[@%]()% 省略n行 """ tmp = [] for i in rare_char: if i in tmp: pass else: tmp.append(i) print i, rare_char.count(i)
运行结果如下：
toddler@HP:~/Desktop$ python 3.py

$ 6046
@ 6157
_ 6112

[ 6108
( 6154
{ 6046
e 1

a 1

可以看到最少字符是equality。这就是过关密码啦。改下url，下一关
