尝试加密并写入文件时，Python中的UnicodeEncodeError

Question

此处（在相同的代码上）第二篇文章。但是这次是一个不同的问题。它只发生每隔一段时间，但它为什么会陷入困境。这是输出和错误：

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

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 + "Encrypting Phrase 20%... " + ":-) " * 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() 

非常感谢你提前，因为这是一个小扩展T I在我的A级设定的任务类。这里有一些你可能已经看到的代码片段，因为在python中有一个加密程序，我从中获取了一些信息。感谢您的时间 ：）。

编辑：如果这有助于它有时太抛出这个错误：

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。所以任何查看这篇文章的人都知道。当你写的写括号里面的文件类型

encoding = "utf8"

所有你需要做的就是把

import codecs

在顶部，然后。希望我已经帮助你解决了这个问题，并感谢所有帮助我得出这个结论的人:-)。
