html = requests.get(url)

html.text

html.content

html.status_code

if html.status_code == 200 :

 print("OK")

 print(html.text)

else: 

  print("connection Fail")

2.2 使用requests模組下載網頁資料

2.4 畫圖

import matplotlib.pyplot as plt

listx =[1,5,7,9]

listy =[15,50,80,40]

plt.plot(listx, listy)

plt.show()

是因為缺少 requests 函示庫

使用pip安裝 requests 函示庫

pip3 install requests
