Question

这里的第二篇文章（在相同的代码上）。然而这次是另一个问题。它只是经常发生，但它让我知道为什么。这是输出和错误：

Phrase to be encrypted: Hello world
Shift keyword, Word only: Hello

:-) :-) :-) Encrypting Phrase 20%... :-) :-) :-)

Here is your Encrypted Phrase:I?j!Qgea:~~[

这是我的代码：

import random

phrase = input('Phrase to be encrypted: ')
shift_key = input("Shift keyword, Word only: ")

Encryption_Base = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890,./;:<>?'@#~]}[{=+-_)(*&^%$£!`¬\|"
key_encryption = random.randint(0, 94)
Cipher = ''

for c in shift_key:
        if c in Encryption_Base:
            Cipher += Encryption_Base[(Encryption_Base.index(c)+key_encryption)%(len(Encryption_Base))]

def Keyword_Encryption(key, phrase):

    if len(phrase) > len(key):
        while len(phrase) > len(key):
            length_to_add = len(phrase) - len(key)
            key = key + key[0:length_to_add]

    elif len(phrase) < len(key):
        while len(phrase) < len(key):
            length_to_sub = len(key) - (len(key) - len(phrase))
            key = key[0:length_to_sub]

    else:
        pass

    shifted_phrase = ''
    for i in range(len(phrase)):
        new_letter = (ord(key[i]) - 96) + (ord(phrase[i]) - 96) + 96
        if new_letter > 1220:
            new_letter = chr(new_letter - 26)

        else:
            new_letter = chr(new_letter)

        shifted_phrase = shifted_phrase + new_letter
    return shifted_phrase

result = Keyword_Encryption(Cipher, phrase)
print (" ")
print (":-) " * 3 + "Encrypting Phrase 10%... " + ":-) " * 3)

print (":-) " * 3 + "Done! " + ":-) " * 3)
print (" ")
print ('Here is your Encrypted Phrase:' + (result) + (Cipher))

file = open("Encrypted.txt", "w")
file.write (str(result) + " " + (Cipher))
file.close()

非常感谢您，因为这是我在A级课程中设置的任务的一个小扩展。这里有一些代码片段你可能已经看过，因为在python中有一个加密程序，我从中获取了一些代码。谢谢您的时间:)。

编辑：如果这有帮助，它有时也会抛出此错误：

Phrase to be encrypted: Hello World
Shift keyword, Word only: Hello
Traceback (most recent call last):
  File "C:\Users\Isaac Scarisbrick\Downloads\Keyword Cipher_1.py", line 42, in <module>
    result = Keyword_Encryption(Cipher, phrase)
  File "C:\Users\Isaac Scarisbrick\Downloads\Keyword Cipher_1.py", line 37, in Keyword_Encryption
    new_letter = chr(new_letter)
ValueError: chr() arg not in range(0x110000)

Answer 1

好。所以看过这篇文章的其他人都知道。您需要做的只是

import codecs

在顶部，然后在您编写文件类型时

encoding = "utf8"

在写括号内。希望我帮助了你的问题，并感谢所有帮助我得出这个结论的人： - ）。

尝试加密和写入文件时Python中的UnicodeEncodeError
