Upload file in S3 using boto3 with Dynamic Foldername

Question

I have 4 S3 buckets : SourceBucket\\folder1\\file1 and DestinationBucket1-folder1, SourceBucket\\folder2\\file1 and DestinationBucket2-folder2. When I upload the folders, I would like the code to check for folder 'DestinationBucket1-folder1' if it exists and then upload the folder1 and files underneath that folder.

I am struggling with S3 KEY. How can I parse S3 KEY and check if the specifice folder exist and then upload the first folder under SourceBucket?

Answer 1

The below code creates the folder if not present and uploads the file:

s3 = boto3.resource('s3', region_name='us-east-2', aws_access_key_id=access_id, aws_secret_access_key=access_key)
s3.meta.client.upload_file(filePath, backet-name, str(foldername) + "/" + str(sub-foldername) + "/" + filename)
