1# Blob Storage — Python SDK Quick Reference
2 
3> Condensed from **azure-storage-blob-py**. Full patterns (SAS tokens,
4> async client, performance tuning, blob properties/metadata)
5> in the **azure-storage-blob-py** plugin skill if installed.

7## Install
8pip install azure-storage-blob azure-identity
9 
10## Quick Start
11```python
12from azure.storage.blob import BlobServiceClient
13from azure.identity import DefaultAzureCredential
14blob_service_client = BlobServiceClient("https://<account>.blob.core.windows.net", DefaultAzureCredential())
15```
16 
17## Best Practices
18- Use DefaultAzureCredential for **local development only** — in production, use ManagedIdentityCredential. See [auth-best-practices.md](../auth-best-practices.md)
19- Use context managers for async clients
20- Set `overwrite=True` explicitly when re-uploading
21- Use `max_concurrency` for large file transfers
22- Prefer `readinto()` over `readall()` for memory efficiency
23- Use `walk_blobs()` for hierarchical listing
24- Set appropriate content types for web-served blobs
