This assumes you are familar with the basic configurations needed to connect to Amazon Web Services (AWS) using Python boto3. If not, check out my article Python (Scripting) - Getting Started with Amazon Web Services (AWS) boto3.

Here is the minimal boilterplate code without error handling to list your Elastic Block Storage (EBS) Volume Snapshots.

#!/usr/bin/python3
import boto3

client = boto3.client('ec2')
response = client.describe_snapshots()
print(response)

Almost always, you are going to want to limit the output, perhaps with owner-id.

#!/usr/bin/python3
import boto3

client = boto3.client('ec2')
response = client.describe_snapshots(Filters=[
        {
            'Name': 'owner-id',
            'Values': [
                '123456789012',
            ]
        },
    ])
print(response)

Or limit the output with volume-id.

#!/usr/bin/python3
import boto3

client = boto3.client('ec2')
response = client.describe_snapshots(Filters=[
        {
            'Name': 'volume-id',
            'Values': [
                'vol-123456789abcdefg',
                'vol-987654321xzynvbd'
            ]
        },
    ])
print(response)

Here is a more practical example, with try/except/else error handling.

#!/usr/bin/python3
import boto3
import sys

try:
  client = boto3.client('ec2')
except Exception as exception:
  print(exception)
  sys.exit(1)

try:
  response = client.describe_snapshots(Filters=[
        {
            'Name': 'volume-id',
            'Values': [
                'vol-123456789abcdefg',
                'vol-987654321xzynvbd'
            ]
        },
    ])
except Exception as exception:
  print(exception)

try:
  response['Snapshots']
except KeyError as keyerror:
  print(keyerror)
else:
  for snapshot in response['Snapshots']:
    for key in snapshot:
      print(f"{key} = {snapshot[key]}")

Something like this should be returned

OwnerId = 123456789012

SnapshotId = snap-09e46801b783ce255
