[python]Create AWS VPC with boto3

Background
This is a follow up on this post https://cyruslab.net/2018/10/19/pythontrying-out-aws-sdk/
back then I was only trying out…
However I am beginning to take this seriously… as a hobby…

Pre-requisites

• Setup awscli. The awscli is used to setup a default connection, by putting your access key id and secret key id, your preferred region and your default output format which i chose json. This output format is for me to process the response after vpc creation method was called.
  The awscli acts as an interface for passing python to my EC2, hence in my code there is no need to specify setup_default_session as default session has already been created by awscli.

• Install boto3 using pip3 install boto3
• Install pyboto3, this is for boto3 methods autocompletion in my pycharm IDE.

import boto3
import ipaddress

ec2_client = boto3.client('ec2')
# boto3 autocomplete https://blog.wavycloud.com/2016/12/27/boto3-pyboto3-autocomplete/
""" :type : pyboto3.ec2 """
user_response = input("Enter VPC subnet:")
try:
    subnet = str(ipaddress.ip_network(user_response))
    response = ec2_client.create_vpc(CidrBlock=subnet)
    # print(type(response['ResponseMetadata']['HTTPStatusCode']))
    # print(response)
    if response['ResponseMetadata']['HTTPStatusCode'] == 200:
        print("VPC, {}, was created successfully at {}".format(response['Vpc']['VpcId'],
                                                               response['ResponseMetadata']['HTTPHeaders']['date']))
    else:
        print("There seems to be a problem fulfilling the request.")
except ValueError as e:
    print(e)

Results

Before the script is triggered, this the default vpc created by AWS.

The response after the script was triggered.

New VPC was created.
