Python爬取天气信息

简单的练手实例，所以进化一下，用面向对象，和输入一个城市查那个城市的七日信息

import sys
import requests
from bs4 import BeautifulSoup
from pypinyin import lazy_pinyin
from requests.exceptions import RequestException
from lxml import etree
import csv

def myInput():
    city = input('请输入你想要查询天气的城市：')
	#city = sys.stdin.readline()
    pinyin_city = lazy_pinyin(city)
    return pinyin_city[0] + pinyin_city[1]
