python 從 url 網址中獲取 csv 和 npy 檔案內容程式碼：

 1 import requests
 2 import numpy as np
 3 from urllib.request import urlopen
 4 import io
 5 
 6 
 7 def url_csv_to_array(url):
 8     response = urlopen(url)
 9     url_content = response.read()
10     url_content_decode = url_content.decode()
11     url_content_list = url_content_decode.split("
 
\n")
12     url_data = []
13     for row in url_content_list[:-1]:
14         row_split = row.split(",")
15         url_data.append([int(i) for i in row_split])
16     url_data_arry = np.array(url_data, dtype=np.int16)
17     return url_data_arry
18     
19 
20 url_csv = "http://.../point.csv"
21 url_data_csv = url_csv_to_array(url_csv)
 
22 
23 
24 def url_read_npy(url_npy):
25     response = requests.get(url_npy)
26     # 判斷返回的Response型別狀態是不是200。如果是200，他將表示返回的內容是正確的，如果不是200，他就會產生一個HttpError的異常。
27     response.raise_for_status()
28     npy_data = np.load(io.BytesIO(response.content))
29     return npy_data
30 
31 
32 url_npy = "http://.../B004_tr.npy
 
"
33 url_data_npy = url_read_npy(url_npy)
