在Python中用另一个彩色字符替换每个字符

问题描述

我正在处理单字母的加密文本，我试图根据每个字母的出现频率猜测原始文本。虽然逐步替换后，当我遇到下面的字母m是我的代码时遇到了错误

`cipher_text = "iyzzfwpmzcyawcixvwxvwciywpfavcwryvvm ywqafrwciywbfs fwhzymvywuywmpmaywcimcwciywrmvbmamgywimvwuyyswcfcmzzewgxvbfkyaygwsfwrfaywbfrrjsxbmcxfsvwvxsbywciyewmaywcwgms yafjvwqfawjvwuewciywpmewciywrfvcwhfhjzmawzyccyavwxswys zxviwmaywycmfxswviagzj"

frequency_letters = {}

for line in cipher_text:
    for char in line:
        if char not in frequency_letters:
            frequency_letters[char]=1
        else:
            frequency_letters[char] += 1



attempt = cipher_text.replace("z","\033[31ml\033[0m")

attempt = attempt.replace("i","\033[31mh\033[0m")
attempt = attempt.replace("c","\033[31mt\033[0m")
attempt = attempt.replace("y","\033[31me\033[0m")
attempt = attempt.replace("w","\033[31m''\033[0m")
attempt = attempt.replace("f","\033[31mo\033[0m")
attempt = attempt.replace("p","\033[31mw\033[0m")
attempt = attempt.replace("a","\033[31mr\033[0m")
attempt = attempt.replace("x","\033[31mi\033[0m")
attempt = attempt.replace("v","\033[31ms\033[0m")

#below is the line that gives an error substituting m to a
#attempt = attempt.replace("m","\033[31ma\033[0m")

print(attempt)


`
When it comes to substituting m to a i get these`[31[31mah[0[31ma[31[31mae[0[31ma[31[31mal[0[31ma[31[31mal[0[31ma[31[31mao[0[31ma[31[31ma''[0[31ma[31[31maw[0[31maa[31[31mal[0[31ma[31[31mat[0[31ma[31[31mae[0[31ma[31[31mar[0[31ma[31[31ma''[0[31ma[31[31mat[0[31ma[31[31mah[0[31ma[31[31mai[0[31ma[31[31mas[0[31ma[31[31ma''[0[31ma[31[31mai[0[31ma[31[31mas[0[31ma[31[31ma''[0[31ma[31[31mat[0[31ma[31[31mah[0[31ma[31[31mae[0[31ma[31[31ma''[0[31ma[31[31maw[0[31ma[31[31mao[0[31ma[31[31mar[0[31ma[31[31mas[0[31ma[31[31mat[0[31ma[31[31ma''[0[31mar[31[31mae[0[31ma[31[31mas[0[31ma[31[31mas[0[31maa [31[31mae[0[31ma[31[31ma''[0[31maq[31[31mar[0[31ma[31[31mao[0[31mar[31[31ma''`

解决方法

我认为最好的解决方案是使用字典并遍历文本

text = "iyzzfwpmzcyawcixvwxvwciywpfavcwryvvm ywqafrwciywbfs fwhzymvywuywmpmaywcimcwciywrmvbmamgywimvwuyyswcfcmzzewgxvbfkyaygwsfwrfaywbfrrjsxbmcxfsvwvxsbywciyewmaywcwgms yafjvwqfawjvwuewciywpmewciywrfvcwhfhjzmawzyccyavwxswys zxviwmaywycmfxswviagzj"

d = {'z': 'l','i': 'h','c': 't','y': 'e','w': "''",'f': 'o','p': 'w','a': 'r','x': 'i','v': 's','m': 'a'}

text_new = ''

for i in range(len(text)):
    try:
        text_new += d[text[i]].upper()
    except:
        text_new += text[i]

print(text_new)

至少使用函数为文本着色也许会更方便。像这样：

cipher_text = "iyzzfwpmzcyawcixvwxvwciywpfavcwryvvm ywqafrwciywbfs fwhzymvywuywmpmaywcimcwciywrmvbmamgywimvwuyyswcfcmzzewgxvbfkyaygwsfwrfaywbfrrjsxbmcxfsvwvxsbywciyewmaywcwgms yafjvwqfawjvwuewciywpmewciywrfvcwhfhjzmawzyccyavwxswys zxviwmaywycmfxswviagzj"

frequency_letters = {}

for line in cipher_text:
    for char in line:
        if char not in frequency_letters:
            frequency_letters[char]=1
        else:
            frequency_letters[char] += 1

def c(character):
    return "\x1b[31m" + character + "\x1b[0m"

attempt = cipher_text.replace("z",c("l"))

attempt = attempt.replace("i",c("h"))
attempt = attempt.replace("c",c("t"))
attempt = attempt.replace("y",c("e"))
attempt = attempt.replace("w",c("''"))
attempt = attempt.replace("f",c("o"))
attempt = attempt.replace("p",c("w"))
attempt = attempt.replace("a",c("r"))
attempt = attempt.replace("x",c("i"))
attempt = attempt.replace("v",c("s"))
attempt = attempt.replace("mm",c("a"))

print(attempt)

或者：

cipher_text = "iyzzfwpmzcyawcixvwxvwciywpfavcwryvvm ywqafrwciywbfs fwhzymvywuywmpmaywcimcwciywrmvbmamgywimvwuyyswcfcmzzewgxvbfkyaygwsfwrfaywbfrrjsxbmcxfsvwvxsbywciyewmaywcwgms yafjvwqfawjvwuewciywpmewciywrfvcwhfhjzmawzyccyavwxswys zxviwmaywycmfxswviagzj"

frequency_letters = {}

for line in cipher_text:
    for char in line:
        if char not in frequency_letters:
            frequency_letters[char]=1
        else:
            frequency_letters[char] += 1

changes = [
    ("z","l"),("i","h"),("c","t"),("y","e"),("w","''"),("f","o"),("p","w"),("a","r"),("x","i"),("v","s"),("mm","a")
]

for what,to in changes:
    cipher_text = cipher_text.replace(what,"\x1b[31m" + to + "\x1b[0m")

print(cipher_text)
