# Store/Get

### Store/get operations

Once the DHT is formed, all participants can `dht.store` key-value pairs in the DHT and `dht.get` them by key:

```python
# first node: store a key-value pair for 600 seconds
store_ok = dht.store('my_key', ('i', 'love', 'hypertensor'),
                     expiration_time=get_dht_time() + 600)

# second node: get the value stored by the first node
value, expiration = dht2.get('my_key', latest=True)
assert value == ('i', 'love', 'hypertensor')
```

As you can see, each value in a subnet DHT is associated with an expiration time, computed current `get_dht_time()` with some offset. This expiration time is used to clean up old data and resolve write conflicts: DHT nodes always prefer values with a higher expiration time and may delete any value past its expiration.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.hypertensor.org/subnet-template/quick-starts/store-get.md?ask=<question>
