+## Using Nano Banana with Python
+
+Guide on how to use Nano Banana aka Gemini 2.5 Flash Image in Python with the [Google GenAI SDK](https://github.com/googleapis/python-genai).
+
+A detailed blog post can be found on [TBD](#).
+
+More resources:
+
+- Get an API key from [Google AI Studio](https://aistudio.google.com/).
+- [Nano Banana Gemini API docs](https://ai.google.dev/gemini-api/docs/image-generation)
+
+## Installation
+
+Install the SDK and Pillow (Pillow is used for image manipulation):
+
+```bash
+pip install -U google-genai
+pip install Pillow
+```
+
+## Image Generation from Text
+
+```python
+from google import genai
+from PIL import Image
+from io import BytesIO
+
+# Configure the client with your API key
+client = genai.Client(api_key="YOUR_API_KEY")
+
+prompt = """Create a photorealistic image of an orange cat
+with a green eyes, sitting on a couch."""
+
+# Call the API to generate content
+response = client.models.generate_content(
+    model="gemini-2.5-flash-image-preview",
+    contents=prompt,
+)
+
+# The response can contain both text and image data.
+# Iterate through the parts to find and save the image.
+for part in response.candidates[0].content.parts:
+    if part.text is not None:
+        print(part.text)
+    elif part.inline_data is not None:
+        image = Image.open(BytesIO(part.inline_data.data))
+        image.save("cat.png")
+```
+
+## Image Editing with Text and Image Inputs
+
+```python
+from google import genai
+from PIL import Image
+from io import BytesIO
+
+client = genai.Client(api_key="YOUR_API_KEY")
+
+prompt = """Using the image of the cat, create a photorealistic,
+street-level view of the cat walking along a sidewalk in a
+New York City neighborhood, with the blurred legs of pedestrians
+and yellow cabs passing by in the background."""
+
+image = Image.open("cat.png")
+
+# Pass both the text prompt and the image in the 'contents' list
+response = client.models.generate_content(
+    model="gemini-2.5-flash-image-preview",
+    contents=[prompt, image],
+)
+
+for part in response.candidates[0].content.parts:
+    if part.text is not None:
+        print(part.text)
+    elif part.inline_data is not None:
+        image = Image.open(BytesIO(part.inline_data.data))
+        image.save("cat2.png")
+```
+
+## Photo restoration with Nano Banana
+
+```python
+from google import genai
+from PIL import Image
+from io import BytesIO
+
+client = genai.Client(api_key="YOUR_API_KEY")
+
+prompt = "Restore and colorize this image from 1932"
+
+image = Image.open("lunch.jpg")  # "Lunch atop a Skyscraper, 1932"
+
+response = client.models.generate_content(
+    model="gemini-2.5-flash-image-preview",
+    contents=[prompt, image],
+)
+
+for part in response.candidates[0].content.parts:
+    if part.text is not None:
+        print(part.text)
+    elif part.inline_data is not None:
+        image = Image.open(BytesIO(part.inline_data.data))
+        image.save("lunch-restored.png")
+```
+
+## Working with Multiple Input Images
+
+```python
+from google import genai
+from PIL import Image
+from io import BytesIO
+
+client = genai.Client(api_key="YOUR_API_KEY")
+
+prompt = "Make the girl wear this t-shirt. Leave the background unchanged."
+
+image1 = Image.open("girl.png")
+image2 = Image.open("tshirt.png")
+
+response = client.models.generate_content(
+    model="gemini-2.5-flash-image-preview",
+    contents=[prompt, image1, image2],
+)
+
+for part in response.candidates[0].content.parts:
+    if part.text is not None:
+        print(part.text)
+    elif part.inline_data is not None:
+        image = Image.open(BytesIO(part.inline_data.data))
+        image.save("girl-with-shirt.png")
+
+```
+
+## Conversational Image Editing
+
+```python
+from google import genai
+from PIL import Image
+from io import BytesIO
+
+client = genai.Client(api_key="YOUR_API_KEY")
+
+# Create a chat
+chat = client.chats.create(
+    model="gemini-2.5-flash-image-preview"
+)
+
+# Make the first image edit
+response1 = chat.send_message(
+    [
+        "Change the cat to a bengal cat, leave everything else the same",
+        Image.open("cat.png"),
+    ]
+)
+
+# display / save image...
+
+# Continue chatting and editing
+response2 = chat.send_message("The cat should be in a sleeping position")
+# display / save image...
+```
