当我使用postgres docker镜像时，我运行
docker run --name mydb -e POSTGRES_PASSWORD=password -d postgres
我看到一个容器在运行。
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a36b98h8982a postgres "docker-entrypoint.s…" 36 minutes ago Up 36 minutes 5432/tcp mydb
所以我制作了Dockerfile，因为我想初始化数据库
FROM postgres:latest
COPY pg-setup.sql /docker-entrypoint-initdb.d/
CMD ['postgres']
但是，当我使用Dockerfile时，容器会立即退出。我如何使其像postgres图像一样运行？
我如何在 Python 中编写代码来执行此操作？我想读取两个多行多文本的字符串，主要是为了比较它们的相似程度（定性）。
s1 = 'I want to read these texts side by side and see how similar they really are'
s2 = 'I really want to read these here texts side by side to see how similar they are (qualitatively)'
print_side_by_side(s1,s2)
输出：
I want to read these texts side by side and see ho I really want to read these here texts side by sid
w similar they really are e to see how similar they are (qualitatively)
