## Usage

When using Javascript, event handlers can be accessed, added, and modified through the map object. With Python, use [`set_event_handlers`](https://docs.foursquare.com/developer/docs/studio-map-sdk-api-reference#set_event_handlers) to set and modify event handlers, and [`remove_event_handlers`](https://docs.foursquare.com/developer/docs/studio-map-sdk-api-reference#remove_event_handlers) to remove event handlers.
