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
import time
from urllib.parse import urlencode
from Crypto.Cipher import AES
from Crypto.Util.Padding import unpad, pad
class AESCipher(object):
key = b'ydsecret://query/key/B*RGygVywfNBwpmBaZg*WT7SIOUP2T0C9WHMZN39j^DAdaZhAnxvGcCY6VYFwnHl'
iv = b'ydsecret://query/iv/C@lZe2YzHtZ2CYgaXKSVfsb7Y4QWHjITPPZ0nQp87fBeJ!Iv6v^6fvi2WN@bYpJ4'
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

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。
