暂停脚本以遵守 Twitter API 限制

Question

我正在使用 Tweepy 从 Twitter 用户名列表中获取一些基本数据。

reader = csv.reader(open('file.csv','rU'))
for row in reader:
    username = row[0]
    try:
        results = api.lookup_users(screen_names = [username])
        for result in results:
            numberoffollowers = result.followers_count
            numberoffriends = result.friends_count
            numberofstatuses = result.statuses_count
            print username, row[1], numberoffollowers, numberoffriends, numberofstatuses, "Completed rows",  row_comp
    except:
            continue

这很好用，但是由于 API 限制是每 15 分钟 180 次调用，我需要将脚本限制为该速率（我不知道该怎么做）。我也不知道 180 次通话之间的停顿应该多长时间——是一分钟，还是 15 分钟？

Answer 1

每 15 分钟 180 次呼叫，即每 5 秒约 1 次呼叫。

 import time

 reader = csv.reader(open('file.csv','rU'))
 for row in reader:
     username = row[0]
     try:
         results = api.lookup_users(screen_names = [username])
         for result in results:
             numberoffollowers = result.followers_count
             numberoffriends = result.friends_count
             numberofstatuses = result.statuses_count
             print username, row[1], numberoffollowers, numberoffriends, numberofstatuses, "Completed rows",  row_comp
             # Wait 5 seconds before doing the next lookup
             time.sleep(5)
     except:
         continue
