Python爬虫系列-有道批量翻译英文单词-注音标版

爬虫系列更新-第二篇文章——《Python爬虫系列-有道批量翻译英文单词-注音标版》

之前发布计算机英文单词时研究了下,怎么把一个含有大量英文单词的txt文件翻译成如下格式：

如上图,左边图片是需要翻译的txt文本,右边图片是翻译后的txt文本。

运行的实际界面效果。

python代码参考了CSDN上的这个作者的帖子，他的分析博文很牛，但是没有批量翻译功能，所以我在他的代码的基础上添加了翻译中文、写入国际音标的功能，全部代码如下：

    iv = hashlib.md5(iv).digest()
    key = hashlib.md5(key).digest()
 
    @staticmethod
    def decrypt(data):
        # AES解密
        cipher = AES.new(AESCipher.key, AES.MODE_CBC, iv=AESCipher.iv)
        decrypted = cipher.decrypt(base64.b64decode(data, b'-_'))
        unpadded_message = unpad(decrypted, AES.block_size).decode()
        return unpadded_message
 
    @staticmethod
    def encrypt(plaintext: str):
        # AES加密
        cipher = AES.new(AESCipher.key, AES.MODE_CBC, iv=AESCipher.iv)
        plaintext = plaintext.encode()
        padded_message = pad(plaintext, AES.block_size)
        encrypted = cipher.encrypt(padded_message)
        encrypted = base64.b64encode(encrypted, b'-_')
        return encrypted

        fout.write(out)
        fout.close()
        print(out)
        print("已完成!")
    

调用方法如下:

把代码保存到.py文件中,运行.py文件,输入需要翻译的txt文本路径地址,如下图所示:

然后翻译后的txt，也会出现在之前的文本文件目录里,如下图:?

?上图中"1.txt"就是输入的英文文档,"1_已翻译.txt"就是翻译后的文档。
