Answer Description

The NoSuchBucket error occurs when a specified bucket does not exist in Amazon S3. When operations such as reading from or writing to an S3 bucket are attempted and the bucket name provided in the request does not exist or is not spelled correctly, the S3 service will respond with a NoSuchBucket error, which is then raised by the AWS SDK as an exception. BucketNotFound and S3BucketMissing are not standard exceptions raised by the AWS SDK for issues regarding nonexistent S3 buckets. While ClientError is a generic exception that might be raised by Boto3, it is not specific to the case where a bucket does not exist.
