Python 无法从其他文件启动tweepy推文刮板

我的tweepy锉刀很好用。它收集所有德国推特。 现在它有时会中断。因此，我想用另一个python文件重新启动它。 Tweepy文件名为“Twython_36”，由my Scraper_Starter.py启动：

import threading
def printit():
    threading.Timer(15.0, printit).start()
    print("Scraper restartet.")
    exec(open("./twython_36.py").read())


printit()

现在我得到了这个错误

Traceback (most recent call last):
  File "<string>", line 42, in on_status
NameError: name 'langid' is not defined

During handling of the above exception, another exception occurred:

只是提出一些想法。但是，您可以使用cron作业，而不是让Python脚本全天候运行。正如错误所说的

NameError:name'sys'未定义

，因此添加缺少的

import sys

，谢谢。导入langid和sys后，它可以工作！只是提出一些想法。但是，您可以使用cron作业，而不是让Python脚本全天候运行。正如错误所说的
