• pyecharts数据可视化


    接上文:https://www.cnblogs.com/yjh1995/p/11836864.html

    需要第三方库:

      pyecharts

    先贴上代码

    import requests
    from bs4 import BeautifulSoup
    from pyecharts.charts import Bar
    from pyecharts import options
    
    #1.发送请求,获取即将上映电影
    response=requests.get('https://movie.douban.com/cinema/later/hangzhou/')
    html_content=response.content.decode('utf-8')
    response.close()
    
    #2.解析html格式的响应内容
    soup=BeautifulSoup(html_content,'lxml')
    all_movies=soup.find('div',id='showing-soon')
    #新建一个列表接收所有电影信息
    all_movies_list=[]
    for each_movie in all_movies.find_all('div',class_='item'):
        tag_a=each_movie.find_all('a')
        tag_li=each_movie.find_all('li')
        movie_name=tag_a[1].text
        movie_link=tag_a[1]['href']
        movie_poster=tag_a[0].find('img')['src']
        movie_date=tag_li[0].text
        movie_type=tag_li[1].text
        movie_area=tag_li[2].text
        movie_want_see=tag_li[3].text.replace('人想看','')
        #打印一下
        print('名字:{name},链接:{link},海报:{poster},上映日期:{date},类型:{type},地区:{area},想看人数:{want_see}'.
              format(name=movie_name,link=movie_link,poster=movie_poster,date=movie_date,type=movie_type,area=movie_area,want_see=movie_want_see))
    
        all_movies_list.append({'名字':movie_name,'链接':movie_link,'海报':movie_poster,'上映日期':movie_date,'类型':movie_type,'地区':movie_area,'想看人数':movie_want_see})
    
    #3.用sorted将所有电影按想看的人数反序排列,x为all_movies_list中的每一个元素
    all_movies_list=sorted(all_movies_list,key=lambda x:int(x['想看人数']))
    
    #4.用pyecharts将所得数据图表化
    #获取所有电影的名字和想看人数作为x、y轴
    all_names=[i['名字'] for i in all_movies_list]
    all_lovers=[i['想看人数'] for i in all_movies_list]
    #设置y轴的轴间距
    movie_bar=Bar(init_opts=options.InitOpts(height='800px'))
    #设置x、y轴
    movie_bar.add_xaxis(all_names)
    movie_bar.add_yaxis('电影关注人数',all_lovers,category_gap="20%")
    #设置系列参数,右边显示y轴的值
    movie_bar.set_series_opts(label_opts=options.LabelOpts(position='right'))
    #x、y轴反转
    movie_bar.reversal_axis()
    #将所得图标保存在文件中
    movie_bar.render('D:\render.html')

    效果图
