      """Create a basic CRUD API for the BlogPost model using Python and Flask.
      The API should include endpoints for creating a post, getting all posts,
      getting a single post, editing a post, and deleting a post.
      
      Example:
      - Endpoint "/post" with POST request should create a new post and return the post ID.
      - Endpoint "/posts" with GET request should return a list of all posts.
      - Endpoint "/post/<id>" with GET request should return a single post with the given ID.
      - Endpoint "/post/<id>" with PUT request should edit the post with the given ID.
      - Endpoint "/post/<id>" with DELETE request should delete the post with the given ID.
