You can use the following code, it worked for me perfectly.

import boto3
ec2 = boto3.resource('ec2')
instance = ec2.create_instances(
    ImageId = 'ami-009d6802948d06e52',
    MinCount = 1,
    MaxCount = 1,
    InstanceType = 't2.micro',
    KeyName = 'nabarupa',
    SubnetId = 'subnet-0yhg678990d56c277')
print (instance[0].id)

Hope this helps.

What happens if I do not mention a subnetID?
If you don't specify a subnet-id then it will create a EC2 in the default VPC.
Thank you. That makes sense.
this command is getting error
What error are you getting @eroor?
botocore.exceptions.ClientError: An error occurred (UnauthorizedOperation) when calling the RunInstances operation: You are not authorized to perform this operation.

i am getting this error
Check if you have all the required access. Your IAM user will require FullAccess to ec2 instances. Also allow programmatic access.
this step is very helpfull thankyou ,

but in lambda it showing following error:

Execution result: failed

  "errorMessage": "Handler 'lambda_handler' missing on module 'lambda_function'",
  "errorType": "Runtime.HandlerNotFound"

but ec2 is creating but showing above msg..please kindly help

You need to define a lambda_handler function in your code. The code is missing the function named lambda_handler.
