使用requests 和 Beautifulsoup搞定天气

首先分析URL结构
http://www.tianqi.com/beijing/
它是由前面http://www.tianqi.com/+地区的拼音+/所构成

import xpinyin
a = xpinyin.Pinyin()
city = pin.get_pinyin(str(input('请输入想要查询的城市：')), '')

这就是获取到你所输入的地区的拼音并将其赋值到city_pinyin对的这一个变量上面去 如果么有下载xpinyin这个包的可以先在终端里面输入pip install xpinyin安装这个包

url = 'https://www.tianqi.com/' + city_pinyin + '/'

将获得的城市拼音添加到https://www.tianqi.com/后就可通过requests库来进行请求，如果么有下载requests这个包的可以先在终端里面输入pip install requests安装这个包

def get_main():
    a = xpinyin.Pinyin()
    city = a.get_pinyin(str(input('请输入想要查询的城市：')), '')  # 获取到该城市的拼音
    url = 'https://www.tianqi.com/' + city_pinyin + '/'  # 在将获取到的城市拼音拼接到网址上去
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36'
    }
    response = requests.get(url, headers=headers).text
    return response

这里是对网址进行请求，得到一个HTML源码之后在通过Beautifulsoup库进行解析

def soups():
    html = BeautifulSoup(get_main(), "html.parser")
    dl = html.find('dl',class_='weather_info')
    title = dl.find('img')['alt']
    times = dl.find('dd', class_="week").get_text()
    shidu = dl.find('dd', class_="shidu")
    kq = str(shidu).split('<dd class="shidu"><b>')[1].split('</b></dd>')[0].split('</b><b>')
    kongqiss = dl.find('dd', class_='kongqi').get_text()
    printjg(title,times,kq,kongqiss)

最后获取到我们想要的数据

def printjg(title,times,kq,kongqiss):
    print(times)
    print(title)
    for i in kq:
        print(i)
    kqzl = re.findall('空气质量：(.*?)PM',kongqiss)
    PM = re.findall('PM:(.*?)日出',kongqiss)
    RCSJ = re.findall('日出:(.*?)日落',kongqiss)
    RLSJ = re.findall('日落:(.*)',kongqiss)
    print('空气质量：'+str(kqzl[0]).strip()+'\n'+'PM：'+str(PM[0]).strip()+'\n'+'日出：'+str(RCSJ[0]).strip()+'\n'+'日落：'+str(RLSJ[0]).strip())

最终代码如下：

import requests
import xpinyin
from bs4 import BeautifulSoup
import re

def get_main():
    pin = xpinyin.Pinyin()
    city_pinyin = pin.get_pinyin(str(input('请输入想要查询的城市：')), '')  # 获取到该城市的拼音
    url = 'https://www.tianqi.com/' + city_pinyin + '/'  # 在将获取到的城市拼音拼接到网址上去
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36'
    }
    response = requests.get(url, headers=headers).text
    return response

def soups():
    html = BeautifulSoup(get_main(), "html.parser")
    dl = html.find('dl',class_='weather_info')
    title = dl.find('img')['alt']
    times = dl.find('dd', class_="week").get_text()
    shidu = dl.find('dd', class_="shidu")
    kq = str(shidu).split('<dd class="shidu"><b>')[1].split('</b></dd>')[0].split('</b><b>')
    kongqiss = dl.find('dd', class_='kongqi').get_text()
    printjg(title,times,kq,kongqiss)

def printjg(title,times,kq,kongqiss):
    print(times)
    print(title)
    for i in kq:
        print(i)
    kqzl = re.findall('空气质量：(.*?)PM',kongqiss)
    PM = re.findall('PM:(.*?)日出',kongqiss)
    RCSJ = re.findall('日出:(.*?)日落',kongqiss)
    RLSJ = re.findall('日落:(.*)',kongqiss)
    print('空气质量：'+str(kqzl[0]).strip()+'\n'+'PM：'+str(PM[0]).strip()+'\n'+'日出：'+str(RCSJ[0]).strip()+'\n'+'日落：'+str(RLSJ[0]).strip())
soups()

制作不易，不喜勿喷，还望支持
