boto3- regions names and service names

Question

How can I get the list of all the regions for eg: us-east-1. How can I get the list of all the regions using boto3. (I am not trying to get the available regions for a particular service as have been asked already)

Also how can I get the names of all the services that AWS provides using boto3 so that I can use them later, when creating resources or clients later on.

I am asking this question because when creating sessions or resources or client I have to specify these things and I don't know how to find the exact value to pass.

To get the list of services in AWS you can perform get_available_services of boto3 Session:

import boto3
boto_session = boto3.session.Session()
list_of_services = boto_session.get_available_services()

print(list_of_services)

which gives you a list of all available services in AWS

Answer 2

For the regions, the closest you can get is describe_regions:

ec2 = boto3.client('ec2')
response = [region['RegionName'] for region in ec2.describe_regions(AllRegions=True)['Regions']]

print(response)

which gives:

['af-south-1', 'eu-north-1', 'ap-south-1', 'eu-west-3', 'eu-west-2', 'eu-south-1', 'eu-west-1', 'ap-northeast-3', 'ap-northeast-2', 'me-south-1', 'ap-northeast-1', 'sa-east-1', 'ca-central-1', 'ap-east-1', 'ap-southeast-1', 'ap-southeast-2', 'eu-central-1', 'us-east-1', 'us-east-2', 'us-west-1', 'us-west-2']

For services - I don't think there is any API call for that. You could scrape them from here, but this would not involve boto3.
