  • 一个完整的大作业

    1.选一个自己感兴趣的主题。
    我选取的是猫途鹰旅游景点
    from bs4 import BeautifulSoup import requests url = 'https://www.tripadvisor.cn/' wb_data = requests.get(url) soup = BeautifulSoup(wb_data.text,'lxml') for i in soup.select('li'): if len(i.select('.ranking'))>0: sort=i.select('.ranking')[0].text #排名 country=i.select('.countryName')[0].text #国家 city=i.select('.cityName')[0].text #城市 hotel=i.select('.hotelsCount')[0].text #酒店数 toury=i.select('.attractionCount')[0].text #景点数 eat=i.select('.eateryCount')[0].text #餐厅数 review=i.select('.reviewTitle')[0].text #印象 print(sort,country,city,review,hotel,toury,eat)

     

     2.写一篇完整的博客,附上源代码、数据爬取及分析结果,形成一个可展示的成果。

    做了一个知了词典的软件

    代码如下

    import urllib.request
    import urllib.parse
    import time
    import random
    import hashlib
    import json
    from window import Application
    from tkinter import *
    from tkinter import Tk,Button,Entry,Label,Text,END
    
    class YouDaoHelper(object):
    
        def __init__(self):
            pass
    
        def crawl(self,content):
            timestamp = int(time.time() * 1000) + random.randint(0, 10)
    
            u = "fanyideskweb"
            d = content
            f = str(timestamp)
            c = "rY0D^0'nM0}g5Mm1z%1G4"
    
            salt = hashlib.md5((u + d + f + c).encode('utf-8')).hexdigest()
    
            data = {
                'i': content,
                'from': 'AUTO',
                'to': 'AUTO',
                'smartresul': 'dict',
                'client': 'fanyideskweb',
                'salt': timestamp,
                'sign': salt,
                'doctypen': 'json',
                'version': '2.1',
                'keyfrom': 'fanyi.web',
                'action': 'FY_BY_CLICKBUTTION',
                'typoResult': 'true'
            }
            data = urllib.parse.urlencode(data).encode('utf-8')
            request = urllib.request.Request(url='http://fanyi.youdao.com/translate_o?'
                                                 'smartresult=dict&smartresult=rule&sessionFrom=', method='POST', data=data)
            response = urllib.request.urlopen(request)
            result_str = response.read().decode('utf-8')
            result_dict = json.loads(result_str)
            result = result_dict['translateResult'][0][0]['tgt']
            return result
    
    
    class Application(object):
    
        def __init__(self):
            self.helper = YouDaoHelper()
            self.window = Tk()
            self.window.title(u'知了词典')  # 创建标题
            self.window.geometry('280x350+600+300')
    
            self.entry = Entry(self.window)  # 创建输入框
            self.entry.place(x=10, y=10, width=200, height=25)  # 放置在哪个地方
    
            self.submit_btu = Button(self.window, text=u'查询', command=self.submit)  # 创建按钮
            self.submit_btu.place(x=220, y=10, width=50, height=25)
    
            # 翻译结果标题
            self.title_label = Label(self.window, text=u'翻译结果:')
            self.title_label.place(x=10, y=55)
    
            # 翻译结果
            self.result_text = Text(self.window, background='#ccc')
            self.result_text.place(x=10, y=75, width=260, height=265)
    
        def submit(self):
            # 1.从输入框中获取用户输入的值
            content = self.entry.get() #get的方法返回当前输入框的内容
            # 2.把这个值发送给有道的服务器,进行翻译
            result = self.helper.crawl(content)
            #3.把结果放置底部的Text控件中
            self.result_text.delete(1.0,END)#把第一个的印记删除
            self.result_text.insert(END,result)#将要输入的内容输入到翻译结果中
    
        def run(self):
            self.window.mainloop()
    
    
    
    if __name__=='__main__':
        app = Application()
        app.run()

    结果如下:
