## Install the Temporal Python SDK
64+
65+
You should install the Temporal Python SDK in your project using a virtual environment. Create a directory for your Temporal project, switch to the new directory, create a Python virtual environment, activate it, and then install the Temporal SDK.
66+
67+
Next, you'll configure a local Temporal Service for development.

## Install Temporal CLI
108+
109+
The fastest way to get a development version of the Temporal Service running on your local machine is to use [Temporal CLI](https://docs.temporal.io/cli).
110+
111+
Choose your operating system to install Temporal CLI.
112+
113+
</SetupStep>
114+
115+
<SetupStep code={
116+
<>
117+
118+
<p>After installing, open a new Terminal window and start the development server:</p>
119+
120+
<CodeSnippet language="bash">
121+
temporal server start-dev
122+
</CodeSnippet>
123+
124+
<div className="port-info">
125+
<h4>Change the Web UI port</h4>
126+
<p>The Temporal Web UI may be on a different port in some examples or tutorials. To change the port for the Web UI, use the <code>--ui-port</code> option when starting the server:</p>
127+
<CodeSnippet language="bash">
128+
temporal server start-dev --ui-port 8080
129+
</CodeSnippet>
130+
<p>The Temporal Web UI will now be available at http://localhost:8080.</p>
131+
</div>
132+
<style>
133+
{`.port-info { background: rgba(68, 76, 231, 0.1); border: 1px solid rgba(68, 76, 231, 0.2); border-radius: 0.75rem; padding: 1.5rem; margin: 1.5rem 0; transition: all 0.3s ease-in-out; box-shadow: 0 2px 4px rgba(0, 0, 0, 0.05); } [data-theme='dark'] .port-info { background: rgba(68, 76, 231, 0.15); border-color: rgba(68, 76, 231, 0.3); } .port-info h4 { margin-top: 0; margin-bottom: 1rem; color: var(--ifm-color-emphasis-900); font-weight: 600; } .port-info p { margin-bottom: 1rem; font-size: 0.95rem; line-height: 1.5; color: var(--ifm-color-emphasis-800); } .port-info p:last-child { margin-bottom: 0; } .port-info code { background: rgba(255, 255, 255, 0.5); padding: 0.2rem 0.4rem; border-radius: 4px; font-size: 0.9em; } [data-theme='dark'] .port-info code { background: rgba(0, 0, 0, 0.2); } @media (max-width: 768px) { .port-info { padding: 1.25rem; } }`}

</style>
135+
</>
136+
}>
137+
138+
## Start the development server
139+
140+
Once you've installed Temporal CLI and added it to your PATH, open a new Terminal window and run the following command.
141+
142+
This command starts a local Temporal Service. It starts the Web UI, creates the default Namespace, and uses an in-memory database.
143+
144+
The Temporal Service will be available on localhost:7233.
145+
The Temporal Web UI will be available at http://localhost:8233.
146+
147+
Leave the local Temporal Service running as you work through tutorials and other projects. You can stop the Temporal Service at any time by pressing CTRL+C.
148+
149+
Once you have everything installed, you're ready to build apps with Temporal on your local machine.

154+
## Run Hello World: Test Your Installation
155+
156+
Now let's verify your setup is working by creating and running a complete Temporal application with both a Workflow and Activity.
157+
158+
This test will confirm that:
159+
160+
- The Temporal Python SDK is properly installed
161+
- Your local Temporal Service is running
162+
- You can successfully create and execute Workflows and Activities
163+
- The communication between components is functioning correctly
164+
165+
### 1. Create the Activity
166+
167+
Create an Activity file (activities.py):
168+
169+
```python
170+
from temporalio import activity
171+
172+
@activity.defn
173+
async def greet(name: str) -> str:
174+
return f"Hello {name}"
175+
```
176+
177+
An Activity is a normal function or method that executes a single, well-defined action (either short or long running), which often involve interacting with the outside world, such as sending emails, making network requests, writing to a database, or calling an API, which are prone to failure.
178+
If an Activity fails, Temporal automatically retries it based on your configuration.
179+
180+
### 2. Create the Workflow
181+
182+
Create a Workflow file (workflows.py):
183+
184+
```python
185+
from datetime import timedelta
186+
from temporalio import workflow
187+
from activities import greet
188+
189+
@workflow.defn
190+
class SayHelloWorkflow:
191+
@workflow.run
192+
async def run(self, name: str) -> str:
193+
return await workflow.execute_activity(
194+
"greet",
195+
name,
196+
schedule_to_close_timeout=timedelta(seconds=10),
197+
)
198+
```
199+
200+
Workflows orchestrate Activities and contain the application logic.
201+
Temporal Workflows are resilient.
202+
They can run and keep running for years, even if the underlying infrastructure fails. If the application itself crashes, Temporal will automatically recreate its pre-failure state so it can continue right where it left off.
203+
204+
### 3. Create the Worker
205+
206+
Create a Worker file (worker.py):
207+
208+
```python
209+
import asyncio
210+
from temporalio.client import Client
211+
from temporalio.worker import Worker
212+
from workflows import SayHelloWorkflow
213+
from activities import greet
214+
215+
async def main():
216+
client = await Client.connect("localhost:7233")
217+
worker = Worker(
218+
client,
219+
task_queue="my-task-queue",
220+
workflows=[SayHelloWorkflow],
221+
activities=[greet],
222+
)
223+
print("Worker started.")
224+
await worker.run()
225+
226+
if __name__ == "__main__":
227+
asyncio.run(main())
228+
```
229+
230+
Run the Worker and keep this terminal running:
231+
232+
```bash
233+
python3 worker.py
234+
```
235+
236+
With your Activity and Workflow defined, you need a Worker to execute them. A Worker polls a Task Queue, that you configure it to poll, looking for work to do. Once the Worker dequeues the Workflow or Activity task from the Task Queue, it then executes that task.
237+
238+
Workers are a crucial part of your Temporal application as they're what actually execute the tasks defined in your Workflows and Activities.
239+
For more information on Workers, see [Understanding Temporal](/evaluate/understanding-temporal#workers) and a [deep dive into Workers](/workers).
240+
241+
Keep this terminal running - you should see "Worker started" displayed.
242+
243+
### 4. Execute the Workflow
244+
245+
Now that your Worker is running, it's time to start a Workflow Execution.
246+
247+
This final step will validate that everything is working correctly with your file labeled `starter.py`.
248+
249+
Create a separate file called `starter.py`:
250+
251+
```python
252+
import asyncio
253+
import uuid
254+
from temporalio.client import Client
255+
256+
async def main():
257+
client = await Client.connect("localhost:7233")
258+
result = await client.execute_workflow(
259+
"SayHelloWorkflow",
260+
"Temporal",
261+
id=f"say-hello-workflow-{uuid.uuid4()}",
262+
task_queue="my-task-queue",
263+
)
264+
print("Workflow result:", result)
265+
266+
if __name__ == "__main__":
267+
asyncio.run(main())
268+
```
269+
270+
Then in a new terminal window, run:
271+
272+
```bash
273+
source venv/bin/activate
274+
python3 starter.py
275+
```
276+
277+
### Verify Success
278+
279+
If everything is working correctly, you should see:
280+
281+
- Worker processing the workflow and activity
282+
- Output: `Workflow result: Hello Temporal`
283+
- Workflow Execution details in the [Temporal Web UI](http://localhost:8233)
