Python批量查单词源码

英语学习中最难的恐怕就是记单词了。通常情况下是利用纸质或者电子词典一个一个查，耗费时间长，效率低，本人用python编写了一款批量查单词的软件，利用python中BeautifulSoup强大的爬虫功能，批量获取海词dict.cn上面的单词发音、词性和语义，甚至是例句，代码如下：

import requests
from bs4 import BeautifulSoup
import re
def read_lst():
    """读取wordlist.txt中的单词"""
    lst=[]
    with open('wordlist.txt',encoding='utf-8') as f:
        lines=f.readlines()
        lst=[i.strip() for i in lines]
    return lst
def look_up(lst):
    """进行单词查询"""
    n=1
    try:
        for i in lst:
            url=r"http://dict.cn/"+i
            r=requests.get(url,timeout=30).text
            recode=r.encode('utf-8')
            soup=BeautifulSoup(recode,"html.parser")
            #爬取单词发音
            html=soup.find('bdo',lang="EN-US")
            phonetic=html.string
            #爬取汉语语义
            html2=soup.find("ul",class_="dict-basic-ul")
            meaning=html2.text.replace("n","")
            #爬取例句
            html3=soup.find("div",class_="layout sort")
            sentence=html3.text.strip()
            s=re.sub("t|nnn","",sentence)
            with open("Wordmeaning.txt","a+",encoding="utf-8") as f:
                f.write(f"{n}. "+i+phonetic+meaning+"n")
                f.write(s+"n") #写入例句
            n+=1
    except Exception as exc:
        print(exc)
if __name__=="__main__":
    uls=read_lst()
    look_up(uls)

如果不想要双语例句，可以直接把html3那一部分删除就可以了。
