Image Generation with Nano Banana - Python Tutorial

This is an image generation tutorial with Google's new model Gemini 2.5 Flash (aka “Nano Banana”). We will learn how to set up the google‑genai Python SDK, get an API key from Google AI Studio, call the generate_content API with mixed text+image inputs, and create identity‑preserving edits, photorealistic text‑to‑image results, e‑commerce product photos, crisp logo designs, and multi‑image compositions.
