大家好，我是编码新手。我想在命令行上运行我的python文件。为此，我首先执行：
docker image build -t se .
使用以下命令启动容器：
docker container run --rm -it --name se -p 5432:5432 se
这使我能够通过端口5432连接到PostgreSQL。
我在命令行上收到以下消息：
2019-11-28 18:50:01.004 UTC [32] LOG: received fast shutdown request

此后，我打开另一个命令窗口并假设我的服务器正在运行，运行python文件
MacBook-Pro:Desktop nousheen$ python3 juiceboard.py
Traceback (most recent call last):
File "juiceboard.py", line 13, in <module>
table = juicetables[0]
IndexError: list index out of range
我不确定该怎么做。有人可以帮我吗？
