如何使用 bash 或终端自动重新运行不断崩溃的进程（python 代码）？

Question

由于 API 限制，我的 Python 代码在从 Twitter 检索信息时不断崩溃。每次崩溃时，我如何才能自动再次运行该进程？

pass尽管我在我的代码中使用了以下代码，但还是发生了这种情况：

from urllib3.exceptions import ProtocolError
import http

except tweepy.TweepError as e:
    print("Tweepy Error is: ", e.reason)
    pass
except http.client.IncompleteRead as e:
    print("http exception is: ", e)
    pass
except UnicodeEncodeError as e:
    print("Unicode error is: ", e)
    pass

#except urllib3.exceptions.ProtocolError as e:
except ProtocolError as e:
    print("url exception is:", e)
    time.sleep(15*60)
    pass
except UnicodeDecodeError as e:
    pass
