# Python

If you have custom Python code, add the `host` parameter to your connection initialization, e.g.

```python
import snowflake.connector

conn = snowflake.connector.connect(
    user="<user>",
    authenticator="oauth",    
    token="<oauth_access_token>",
    account="<account>",
    host="<your_host>.espressocomputing.com",
)
```
