+description: Use Notion API Python SDK to create pages, append blocks, and manage content in Notion. Triggers on "Notion", "同步到Notion", "notion API".
+---
+
+# Notion API Python SDK
+
+Create and populate Notion pages programmatically.
+
+## Setup
+
+```bash
+pip install notion-client
+```
+
+Set environment variables: `NOTION_API_KEY` (integration token), `NOTION_PAGE_ID` (parent page ID).
+
+## Create Page
+
+```python
+from notion_client import NotionClient
+import os
+
+client = NotionClient(auth=os.environ["NOTION_API_KEY"])
+page = client.pages.create(
+    parent={"page_id": os.environ["NOTION_PAGE_ID"], "type": "page_id"},
+    properties={
+        "title": [{"type": "text", "text": {"content": "Title"}}]
+    }
+)
+page_id = page["id"]
+```
+
+## Append Blocks
+
+```python
+client.blocks.children.append(block_id=page_id, children=[
+    {"type": "heading_2", "heading_2": {"rich_text": [{"type": "text", "text": {"content": "Section"}}]}},
+    {"type": "paragraph", "paragraph": {"rich_text": [{"type": "text", "text": {"content": "Text."}}]}},
+    {"type": "code", "code": {"language": "python", "rich_text": [{"type": "text", "text": {"content": "code"}}]}},
+])
+```
+
+## Column Layout
+
+Content goes in nested `children` of `column`/`column_2` inside `column_list`:
+
+```python
+{"type": "column_list", "column_list": {"children": [
+    {"type": "column", "column": {"children": [left_block]}},
+    {"type": "column", "column": {"children": [right_block]}},
+]}}
+```
+
+## Block Types
+
+- `heading_1/2/3`, `paragraph`, `code` (with `language`), `bulleted_list_item`, `numbered_list_item`
+- `column_list` / `column`, `bookmark`, `divider`, `to_do`, `callout`
+- Rich text: `{"type": "text", "text": {"content": "..."}, "annotations": {"bold": true}}`
+
+## Database Pages
+
+Properties must match the database schema exactly — unknown keys cause `ValidationError`.
