 - `RateLimitException` in the Python SDK
 
 For example, if you're on the Pro tier (without any concurrency add-ons), you can create up to 100 sandboxes running concurrently.
 If the 100 sandboxes are still running, requests for creating new sandboxes from the SDKs (`Sandbox.create()` in JS/TS or `Sandbox.create()` in Python) will fail and return `RateLimitError` or `RateLimitException` respectively.
 Once the number of running sandboxes drops below 100, or you purchase a concurrency add-on, you’ll be able to create new sandboxes again.
