practice之Python爬取百度翻译页面

1.获取需求

from urllib import request,parse
import json

2.根据需求，寻找网站

url = 'http://fanyi.baidu.com/sug'

3.定义函数传入需要进行翻译的数据,转换为字符串后并将网站数据获取到本地、解析json并打印翻译结果

def translate(kw):
    form = {
        'kw':kw
    }
    form_str = parse.urlencode(form)
    
    form_bytes = form_str.encode('utf-8')

    response = request.urlopen(url,data = form_bytes)

    res_dict = json.loads(response.read().decode('utf-8'))

    result = res_dict['data'][0]['v']

    return result

4.测试代码

if __name__ == '__main__':
    res = translate('篮球')
    print(res)
    
    res = translate('足球')
    print(res)

6.测试返回的内容

[lán qiú] basketball;
[zú qiú] football; soccer; association football; c
