how to create file in aws S3 using python boto3

Question

I want to create an empty file in AWS s3 using python.

I'm using boto3 and python.

I want to know apart from the put method is there any way to create files in s3?

Answer 1

Assuming that you genuinely want a zero-byte file, you can do it as follows:

import boto3

s3 = boto3.client('s3')

s3.put_object(
    Bucket='mybucket',
    Key='myemptyfile'
)

Note the lack of a Body parameter, resulting in an empty file.

Similarly, you can create a 'folder' in S3 as follows. This is basically what the AWS console does when you ask it to create a folder. But note that, in general, folders aren't necessary and don't typically exist in S3 (see Notes on S3 Object Store in this answer).

import boto3

s3 = boto3.client('s3')

s3.put_object(
    Bucket='mybucket',
    Key='myemptyfolder/'
)

Answer 2

You can use upload_file() method :

s3_resource.Bucket(bucket_name).upload_file(Filename = "file_name" , Key = "key")
