python challenge第1关--NoteBook上的“乱码”

在 python challenge第0关 中已经得到第1关的地址了:

一、观察地址栏和标签:


What about making trans?

 考虑下转换?

map 有映射之意。



二、


笔记本上写着"K->M","O->Q","E->G"。

黄色提示:

"everybody thinks twice before solving this"

乱码:

"g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj."


"K->M","O->Q","E->G" 的转换规则是不是对应着“twice”呢?

只要按此规则解密即可。 g->i, f->h, m->o 以此类推。

转换后的密文为:

"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."



不要手动转换,应该使用python代码转换。

now apply on the url ,对url转换,也即,对map 转换即可:

得到地址:
