我有快照列表，但我想获得SnapshotName和大小，SnapshotID使用boto3 python

import boto3

# 创建EC2客户端
ec2_client = boto3.client('ec2')

# 获取快照列表
response = ec2_client.describe_snapshots()

# 遍历快照列表并获取SnapshotName和大小
for snapshot in response['Snapshots']:
    snapshot_id = snapshot['SnapshotId']
    snapshot_name = snapshot['Tags'][0]['Value'] if 'Tags' in snapshot and len(snapshot['Tags']) > 0 else 'N/A'
    snapshot_size = snapshot['VolumeSize']
    
    print("Snapshot ID: ", snapshot_id)
    print("Snapshot Name: ", snapshot_name)
    print("Snapshot Size: ", snapshot_size, "GB")
    print("------------------------------")
