| 14 | + |
| 15 | +Dapr offers a variety of subpackages to help with the development of Python applications. Using them you can create Python clients, servers, and virtual actors with Dapr. |
| 16 | + |
| 17 | +## Prerequisites |
| 18 | + |
| 19 | +- [Dapr CLI]({{% ref install-dapr-cli.md %}}) installed |
| 20 | +- Initialized [Dapr environment]({{% ref install-dapr-selfhost.md %}}) |
| 21 | +- [Python 3.9+](https://www.python.org/downloads/) installed |
| 22 | + |
| 23 | +## Installation |
| 24 | + |
| 25 | +To get started with the Python SDK, install the main Dapr Python SDK package. |
| 26 | + |
| 27 | +{{< tabpane text=true >}} |
| 28 | + |
| 29 | +{{% tab header="Stable" %}} |
| 30 | +<!--stable--> |
| 31 | +```bash |
| 32 | +pip install dapr |
| 33 | +``` |
| 34 | +{{% /tab %}} |
| 35 | + |
| 36 | +{{% tab header="Development" %}} |
| 37 | +<!--dev--> |
| 38 | +> **Note:** The development package will contain features and behavior that will be compatible with the pre-release version of the Dapr runtime. Make sure to uninstall any stable versions of the Python SDK before installing the dapr-dev package. |
| 39 | +
|
| 40 | +```bash |
| 41 | +pip install dapr-dev |
| 42 | +``` |

| 51 | +### SDK imports |
| 52 | + |
| 53 | +Python SDK imports are subpackages included with the main SDK install, but need to be imported when used. The most common imports provided by the Dapr Python SDK are: |

| 81 | +### SDK extensions |
| 82 | + |
| 83 | +SDK extensions mainly work as utilities for receiving pub/sub events, programatically creating pub/sub subscriptions, and handling input binding events. While you can acheive all of these tasks without an extension, using a Python SDK extension proves convenient. |
