How can I set up networking in Docker Compose for my Python app?

To set up networking in Docker Compose, you can define networks in your docker-compose.yml file. Would you like an example?

Yes, please provide an example of the docker-compose.yml file.

Here's a simple example:

version: '3'
services:
  web:
    image: python:3.8
    networks:
      - mynetwork
  db:
    image: postgres
    networks:
      - mynetwork
networks:
  mynetwork:

This creates a network called mynetwork that both services can use.

How do I connect to the database from my Python app?

You can connect to the database using the service name as the hostname. For example, use db as the hostname in your connection string.
