How can I easily determine if a Boto 3 S3 bucket resource exists?

Question

For example, I have this code:

import boto3

s3 = boto3.resource(\'s3\')

bucket = s3.Bucket(\'my-bucket-name\')

# Does it exist???

Answer 1

Use lookup Function -> Returns None if bucket Exist

if s3.lookup(bucketName) is None:
    bucket=s3.create_bucket(bucketName) # Bucket Don't Exist
else:
    bucket = s3.get_bucket(bucketName) #Bucket Exist
