本文实例为大家分享了python爬虫实现中英翻译词典的具体代码，供大家参考，具体内容如下
通过根据某平台的翻译资源，提取出翻译信息，并展示出来，包括输入，翻译，输出三个过程，主要利用python语言实现（python3.6），抓取信息展示。
import urllib.request
import urllib.parse
import json
def en_zh(content):
url = 'http://fanyi.baidu.com/v2transapi'
head = {}
head['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36'
data={}
data['from'] = 'en'
data['to'] = 'zh'
data['query'] = content
data['transtype'] = 'translang'
data['simple_means_flag'] = '3'
data = urllib.parse.urlencode(data).encode('utf-8')
req =urllib.request.Request(url,data,head)
response=urllib.request.urlopen(req)
html = response.read().decode('utf-8')
target = json.loads(html)
print("翻译结果：%s" %(target['trans_result']['data'][0]['dst']))
def zh_en(content):
url = 'http://fanyi.baidu.com/v2transapi'
data={}
data['from'] = 'zh'
data['to'] = 'en'
data['query'] = content
data['transtype'] = 'translang'
data['simple_means_flag'] = '3'
data = urllib.parse.urlencode(data).encode('utf-8')
req =urllib.request.Request(url,data)
req.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36')
response=urllib.request.urlopen(req)
html = response.read().decode('utf-8')
target = json.loads(html)
print("翻译结果：%s" %(target['trans_result']['data'][0]['dst']))
while(True):
content = input("请输入要翻译的内容(按q退出)：")
if content=='q':
input("您已退出，欢迎再次使用")
break
en_zh(content)
zh_en(content)
