How to create S3 bucket using AWS Lambda python?

Question

I am creating a AWS Lambda function using Python. I want to create S3 bucket but I am getting error as the bucket name provided by me is not JSON serializable.

Here is the code I used for creating a bucket with Lambda:

import boto from boto 
import s3 from boto.s3.connection 
import S3Connection

def lambda_handler(event, context):
  conn = S3Connection('access_key','secret_access_key')
  print "Connection:",conn
  bucket = conn.create_bucket('bucketname')
  print bucket
  return bucket

Please provide the code you are using and the error message you are experiencing. For tips on asking a good question, please see: How do I ask a good question? — John Rotenstein

Feel free to Edit your question rather than adding code in a comment. Within a Lambda function, there is no need to obtain an Access Key and Secret Key. It is automatically provided as a result of assigning a Role to the Lambda function. Did you Lambda function work? What error did you receive? You can view the log in Amazon CloudWatch Logs. — John Rotenstein

From Creating and Using Amazon S3 Buckets boto3 documentation:

import boto3

s3 = boto3.client('s3')
s3.create_bucket(Bucket='my-bucket')

Rules for bucket names:

The bucket name can be between 3 and 63 characters long, and can contain only lower-case characters, numbers, periods, and dashes.
Each label in the bucket name must start with a lowercase letter or number.
The bucket name cannot contain underscores, end with a dash, have consecutive periods, or use dashes adjacent to periods.
The bucket name cannot be formatted as an IP address (198.51.100.24).

I followed all the rules for S3 bucket.

this worked for me s3 = boto3.resource('s3') b = s3.Bucket('laddu47') b.create(CreateBucketConfiguration={ 'LocationConstraint': 'ap-south-1' })
