It looks like you've provided a solution in command line above, do you have a solution that would work to be run from a python script on an EC2 instance?

Both the script and the command will have the same result, running them on the EC2 instance will download the file to the EC2 instance. No other solutions possible. Do I use boto3 to copy it from the EC2 instance? Where can i find documentation on this?

You can copy with scp if you have ssh access from your local machine to the EC2 instance. Honestly, the simplest way is to run the command or script directly on your local machine.

Erik - thanks. The whole goal here is to be able to run everything from the cloud; I'm using this python script on the EC2 instance, and scheduling it to run once a day with crontab. Ideally, I'd like to find some way to output the file from s3 to my local machine without having to run the python script locally. The big problem here is because usually, Local Machines don't have a private IP. If your local machine has, you could install SCP server in your local machine and then automate the script to run a SCP command to send the file to your local machine.

This is very helpful, but I need to upload the files to another bucket and would like to create a bucket if it does not exist and then upload the file. I am very new to Python and I wanted to use the code above as a template to upload files from a directory to an s3 bucket.

In the code above where do I put in the path to my source file the directory. Works well but this is quite slow though. Your email address will not be published.
