**To list the event source mappings for a function**

The following ``list-event-source-mappings`` example displays a list of the event source mappings for the ``my-function`` Lambda function. ::

    aws lambda list-event-source-mappings \
        --function-name my-function

Output::

    {
        "EventSourceMappings": [
            {
                "UUID": "a1b2c3d4-5678-90ab-cdef-11111EXAMPLE",
