我需要5x5中组合了字母和密钥的字符数组形式的结果: import numpy as np
def playfair():
key=input("Enter the secret key")
key+='abcdefghiklmnopqrstuvwxyz'
size=len(key)
for i in range(size):
if key[i]=='j':
key[i]='i'
for j in range(i+1,size):
我正在尝试用Playfair方法使python加密和解密文本。但我遇到了一个障碍,因为它似乎在每行输出输出时都输出"None“。如果有人告诉我为什么会这样做,我将不胜感激。(这是我的第一篇文章,所以请容忍我可能犯的任何错误)。我的代码:
def cip():
key=input(print("Please Enter Keyword: "))
return key
def inp():
c = int(input(print("1.Cipher text \n2.Exit\n\t>>")))
if c==1:
我正在寻找一个R解决方案来解决解析引号文本文件的问题(如下所示),给出一个data.frame,每个引号有一个观察,变量text和source如下所述。
