【python】book爬蟲、數據清洗與可視化實戰2

import requests
import time
import pandas as pd

# 加載pymongo庫i
import pymongo
#建立連接
client = pymongo.MongoClient('localhost',27017)
# 在MongoDB中新建名爲weather的數據庫
book_weather=client['weather']
# 在weather庫中新建名爲sheet_ weather_ 3的表
sheet_weather = book_weather['sheet weather_ 3']
data=pd.read_csv(open('H:/new file 2/python_project/wethear API/china-city-list.csv',encoding ='utf-8'))
data1 = data.iloc[1:,0]#通過iloc（行列號）索引
for item in data1[0:10]:
    url = 'https://free-api.heweather.net/s6/weather/now?location='+ item +'&key=b09b35a6293e41d29c9e9813de84673c'
    strhtml = requests.get(url)
    strhtml.encoding = 'utf8'
    time.sleep(1)
    dic = strhtml.json()
    for item in dic["HeWeather6"][0]["now"]["wind_dir"]:
        print(item);
      # 向表寫入一條數據(真正核心的就下面一句唄)
        sheet_weather.insert_one(dic)
