凯撒密码python编程 python编写凯撒代码简单

def use_list(): str_before=input(＂请输入明文:＂) str_change=str_before.lower() str_list=list(str_change) str_list_change=str_list i=0 whilei<len(str_list): iford(str_list[i])<.

def caesar_cipher(s, key=2): return ''.join((chr(ord(ch) + key) for ch in s))

凯撒密码是对字母表整体进行偏移的一种变换加密.因此,建立一个字母表,对明文中每个字母,在这个字母表中偏移固定的长度即可得到对应的密文字母.最基本的实现.

s = raw_input('[开始加密]please input your str:') s = list(s) n = 0 for sw in s: s[n] = chr(ord(sw)+3) n = n + 1 sout = '' for sw2 in s: sout = sout + sw2 print '[加密结果]:',sout解密的类似,主要用到ord、chr函数.

# codinng=utf-8 x = 'a b c d e f g h i j k l m n o p q r s t u v w x y z'.split(' ') y = 'n o p q r s . 键为原字符串, 值为加密字符串# 定义凯撒加密函数, 输入字符串, 输出凯撒加密.

printf(＂求求你编个凯撒密码的程序吧.\n＂);

//1. math.ceil()用作向上取整. <br><br>//2. math.floor()用作向下取整. <br> alert(math.ceil(10/3));//4 <br><br>alert(math.floor(10/3));//3 <br>alert(math.round(10/3));//3

输入:CAT 输出:DBU import string def caesar_shift(s): # Write your code here # To print results to the standard output you can use print # Example: print ＂Hello world!＂ table = string.maketrans(string.ascii_uppercase, string.asc.

凯撒加密(JAVA版的,亲,不要太感谢我,求采纳- -!!):public class Encryption {private static char encry(char c){if(c>=97 && c<=123){if(c == 'x'){c = 'a' ;}else if(c == 'y').
