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) Volumes.

#!/usr/bin/python3
import boto3

client = boto3.client('ec2')
response = client.describe_volumes()
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_volumes()
except Exception as exception:
  print(exception)

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

Something like this should be returned
