使用 CSV 文件存储

将爬取到的数据以 CSV 文件形式存储：

import csv
import requests

req = requests.get("http://www.baidu.com/")

data = {
    'status_code': req.status_code,
    'url': req.url,
    'cookies': req.cookies,
}

# 写入到CSV文件
with open('/tmp/1.csv', 'w') as csvfile:
    fieldnames = ['status_code', 'url', 'cookies']
    write = csv.DictWriter(csvfile, fieldnames=fieldnames)
    write.writerow(data)

# 从CSV文件中读取数据
with open('/tmp/1.csv', 'r') as csvfile:
    reader = csv.reader(csvfile)
    for row in reader:
        print(row)
