Development prerequisites

To use OpenAI Agents SDK, you need more than just a working installation and environment. The SDK is designed with specific Pythonic architectural patterns in mind, and being familiar with these principles will make using the SDK a lot easier. In this section, we will go through a quick primer on three key Python principles needed to use the SDK.

Note that this is not an exhaustive Python tutorial. Learning Python fundamentals is outside the scope of this course. This section, though, will align you with the techniques used in the SDK examples throughout this book.

Python functions architecture

The SDK is used via Python code, so you’ll be writing your own functions and maybe classes to extend agent capabilities. For example, the Agents SDK allows you to define tools as simple Python functions that the agent can call. As a result, you should be familiar with how to create and use Python functions:

# An example Python function
def echo...
