以上代码在stop_words = set(stopwords.words('english') + list(string.punctuation))处报错LookupError，请问如何处理

这个错误通常是由于缺少必要的语料库文件导致的。你可以尝试运行以下代码：

import nltk
nltk.download('stopwords')

这将下载英语停用词列表所需的语料库文件。然后，你可以再次尝试运行你的代码，并且应该不会再遇到LookupError错误了。

import string """移除标点符号""" if __name__ == '__main__': # 方式一 # s = 'abc.' text_list = "Hello Mr. Smith, how are you doing today? The weather is great, and city is awesome." text_list = text_list.translate(str.maketrans(string.punctuation, " " * len(string.punctuation))) # abc print("s: ", text_list)

这段代码使用Python标准库中的`string`模来移除给定文本中的标点符号。

在代码中，首先导入`string`模块。然后，定义字符串变量`text_list`，其中包一段文本。

接下来，使用`_list.translate()`方法，传入`str.maketrans(string.punctuation, " " * len(string.punctuation))`作为参数。这个方法会根据提供的转换表来删除文本中的标点符号。具体来说，`str.maketrans()`函数会创建一个用于字符替换的转换表，将标点符号替换为相应长度的空格。然后，`text_list.translate()`方法会将文本中的标点符号替换为空格。

最后，通过`print("s: ", text_list)`打印出移除标点符号后的文本。

运行该段代码，你将得到以下输出：

s:  Hello Mr  Smith  how are you doing today  The weather is great  and city is awesome 

标点符号已被替换为空格。

这段代码缺少一些必要的库和变量定义，我假设你想使用一个密码字典文件来进行暴力破解。以下是更改后的代码：

import string
import itertools
import rarfile
import concurrent.futures
from Crypto.Cipher import ARC4

def gen_password(passwd):
    key = passwd.encode()
    cipher = ARC4.new(key)
    return cipher

rar_path = "E:/Edge浏览器下载/30.rar"

def try_passwords(rar_path, dictionary_file, max_workers=4):
    rar = rarfile.RarFile(rar_path)
    tested = set()
    with open(dictionary_file, 'r') as f:
        dictionary = f.read().splitlines()
    with concurrent.futures.ProcessPoolExecutor(max_workers) as executor:
        fs = []
        for password in dictionary:
            password_str = password.strip()
            if password_str in tested:
                continue
            tested.add(password_str)
            decrypt_pwd = gen_password(password_str)
            fs.append(executor.submit(rar.extractall, pwd=decrypt_pwd))
        for index, future in enumerate(concurrent.futures.as_completed(fs)):
            try:
                future.result()
                print(f'成功!密码是: {dictionary[index]}')
                return dictionary[index]
            except (rarfile.BadRarFile, rarfile.RarWrongPassword):
                pass

result = try_passwords(rar_path, 'passwords.txt')
print(result)

你需要将 `passwords.txt` 替换为你自己的密码字典文件路径。
