从网络获取数据

示例代码：

import os
import requests
import pandas as pd

# 发送get请求，获取网页数据（tsv文件）
url = 'https://raw.githubusercontent.com/udacity/new-dand-advanced-china/master/%E6%95%B0%E6%8D%AE%E6%B8%85%E6%B4%97/WeRateDogs%E9%A1%B9%E7%9B%AE/image-predictions.tsv'
res = requests.get(url)

# 创建文件夹
folder_name = 'data'
if not os.path.exists(folder_name):
    os.makedirs(folder_name)

# 输出到文件
file_name = url.split('/')[-1]
with open(os.path.join(folder_name, file_name), mode='wb') as file:
    file.write(res.content)

# 再用pandas读取tsv文件
pd.read_table(os.path.join(folder_name, file_name))
