Hey @Neha, you can create NLB using boto itself. Follow these steps:

• Create NLB using Boto

import boto3

client = boto3.client('elbv2')
client.create_load_balancer(Name='my-load-balancer', Type='network')

Provision the LB

CloudFormation Template - my-nlb-stack.yml

Resources:
  NetworkLoadBalancer:
    Type: "AWS::ElasticLoadBalancingV2::LoadBalancer"
    Properties:
      Name: my-network-lb
      Type: network
      Subnets:
        - subnet-aabbccdd
        - subnet-ddeeff11
        - subnet-22334455
Outputs:
  MyNLB:
    Description: The ARN of the newly provisioned NLB
    Value: !Ref NetworkLoadBalancer
