def describe_volumes(DryRun=None, VolumeIds=None, Filters=None, NextToken=
    None, MaxResults=None):
    """
    Describes the specified EBS volumes.
    If you are describing a long list of volumes, you can paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeVolumes request to retrieve the remaining results.
    For more information about EBS volumes, see Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide .

    Examples
    This example describes all of your volumes in the default region.
    Expected Output:
    This example describes all volumes that are both attached to the instance with the ID i-1234567890abcdef0 and set to delete when the instance terminates.
    Expected Output:

    :type DryRun: boolean
    :param DryRun: Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

    :type VolumeIds: list
    :param VolumeIds: One or more volume IDs.

    :type Filters: list
    :param Filters: One or more filters.
            attachment.attach-time - The time stamp when the attachment initiated.
            attachment.delete-on-termination - Whether the volume is deleted on instance termination.
            attachment.device - The device name that is exposed to the instance (for example, /dev/sda1 ).
            attachment.instance-id - The ID of the instance the volume is attached to.
            attachment.status - The attachment state (attaching | attached | detaching | detached ).
            availability-zone - The Availability Zone in which the volume was created.
            create-time - The time stamp when the volume was created.
            encrypted - The encryption status of the volume.
            size - The size of the volume, in GiB.
            snapshot-id - The snapshot from which the volume was created.
            status - The status of the volume (creating | available | in-use | deleting | deleted | error ).
            tag :key =*value* - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify tag:Purpose for the filter name and X for the filter value.
            tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter 'tag-key=Purpose' and the filter 'tag-value=X', you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag :key =*value* filter.
            tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.
            volume-id - The volume ID.
            volume-type - The Amazon EBS volume type. This can be gp2 for General Purpose SSD, io1 for Provisioned IOPS SSD, st1 for Throughput Optimized HDD, sc1 for Cold HDD, or standard for Magnetic volumes.
            (dict) --A filter name and value pair that is used to return a more specific list of results. Filters can be used to match a set of resources by various criteria, such as tags, attributes, or IDs.
            Name (string) --The name of the filter. Filter names are case-sensitive.
            Values (list) --One or more filter values. Filter values are case-sensitive.
            (string) --
            
            

    :type NextToken: string
    :param NextToken: The NextToken value returned from a previous paginated DescribeVolumes request where MaxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the NextToken value. This value is null when there are no more results to return.

    :type MaxResults: integer
    :param MaxResults: The maximum number of volume results returned by DescribeVolumes in paginated output. When this parameter is used, DescribeVolumes only returns MaxResults results in a single page along with a NextToken response element. The remaining results of the initial request can be seen by sending another DescribeVolumes request with the returned NextToken value. This value can be between 5 and 500; if MaxResults is given a value larger than 500, only 500 results are returned. If this parameter is not used, then DescribeVolumes returns all results. You cannot specify this parameter and the volume IDs parameter in the same request.
