爬蟲的起點，獲取網頁程式碼

#!/usr/bin/env python3
# -*- encoding:utf-8 -*-

# 請求網頁程式碼

import urllib.request

req = urllib.request.Request('http://www.weather.com.cn/adat/sk/101280101.html')

r = urllib.request.urlopen(req)

result = str(r.read(), encoding='utf-8')

print(result, type(result))

# requests是第三方模組，與上面urllib.request一樣的效果。而且跟方便簡潔

import
 
 requests

res = requests.get("http://www.weather.com.cn/adat/sk/101280101.html")

res.encoding = 'utf-8'

r = res.text

print(type(r), r)
