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:

import hashlib
import base64
import requests
import json

from urllib.parse import urlencode
from Crypto.Cipher import AES
from Crypto.Util.Padding import unpad, pad
 
 
class AESCipher(object):

    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

        #print(out)
        return out
    except Exception as e:
        print('翻译失败:', e)
        return 0
        
if __name__ == '__main__':
    path = input("请输入你要翻译的txt文档路径(E:\1.txt): ")
    # result = translate(word)
    out = ""
    with open(path,'r') as f:
        lines = f.readlines()
        for line in lines:
            print(line.replace("\n","").replace("\r",""))
            result = translate(line)#'zh-CHS', 'ja')
            if result:
                out =  out + line.replace("\n","").replace("\r","") + " " + result + "\n"
            #print(out)
    #print('翻译结果:\n', result)
        f.close()
    with open(path[:-4] + "_已翻译.txt",'w',encoding='utf-8') as fout:
        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。
