**To retrieve information about a Lambda layer version**

The following ``get-layer-version-by-arn`` example displays information about the layer version with the specified Amazon Resource Name (ARN). ::

    aws lambda get-layer-version-by-arn \
        --arn "arn:aws:lambda:us-west-2:123456789012:layer:AWSLambda-Python37-SciPy1x:2"

Output::
