Run your first Agent SDK query
The Claude Agent SDK lets you drive Claude Code from a Python script instead of the terminal. Importing query from claude_agent_sdk gives you an async iterator: you pass it a prompt and loop over the messages it streams back as Claude works.
The SDK is already available in this session, and a small orders.py is in your working directory. Complete the script so it asks Claude to summarize that file, then prints each streamed message.
This exercise is part of the course
Claude Code in Action
Exercise instructions
- Inside the
async forloop, callquery()with apromptdescribing the task. - Run the
main()coroutine by passing it toasyncio.run().
