Need to create a snapshot of a volume using python3 and boto3 for a specific region

Question

I am having a need to create snapshot of all volumes present in a region in aws. This script must be able to create snapshot of all the volumes in us-east-2 region

I have used the below script but its only taking snapshot of my default region. How to fix this issue?

import boto3
ec2 = boto3.resource('ec2')
snapshot = ec2.Snapshot('id')

Region='us-east-2'

for vol in ec2.volumes.all():
    if Region=='us-east-2':
        string=vol.id
        ec2.create_snapshot(VolumeId=vol.id,Description=string)
        print(vol.id),
        print('A snapshot has been created for the following EBS volumes',vol.id)
    else:
        print('No snapshot has been created for the following EBS volumes',vol.id)

The script works fine only for default region but when I create volumes in any other region it does not bother to take snapshot of those volumes. Can someone please help?

You may specify the region in creating ec2 client with Config.

Thanks I used client to specify the region and I have updated the answer with my script as well in case if someone else faces the same senario. – sidharth vijayakumar May 17 '22 at 04:48

After doing more research I could see that the below script worked fine for me.

import boto3

ec2 = boto3.client('ec2')
region_name='us-east-2'

ec2 = boto3.resource('ec2',region_name)
count=0

for vol in ec2.volumes.all():
    count+=1
    string=vol.id
    ec2.create_snapshot(VolumeId=vol.id,Description=string)
    print('A snapshot has been created for the following EBS volumes',vol.id)
if count==0:
        print('No snapshot has been created for the following region, cause volume does not exit!')
