In this section we will go over on how to download a file using Boto3 S3, similar to uploading a file to S3 we will implement the download functionality:. The code above will download from our bucket the previously two files we uploaded to it. The answer is no because the last argument of the download file is the destination path.

Lets demonstrate the execution of this example:. Next we will discuss on how to list files using Boto3 S3 from our bucket. This is particularly useful when scripting code as a batch job that runs periodically and also acts as a verification that your data is there when it should be.

In the instance above we are not applying any filters on the objects we are requesting but we can easily do that if we wanted too. For example lets say we had a folder in our bucket called sub-folder and wanted to list all the items in it we would be adjusting the code to look like this:.

In our case since we do not have a sub-folder directory it will not return any results if we were to execute the new code. One common question that I always get is:. However you can always request all the files in a directory and then using python you can check the extension of the file and see if it matches what you are looking for. So for example a simple if condition would do that.

Finally we will talk about how to delete files using Boto3 S3. Since we have covered most of the aspects on using Boto3 alongside with S3 lets cover the last part which is deleting files from your bucket folder. The difference between listing and deleting is actually very minor in the code. The idea is you still follow similar steps on getting an object and based on the object or list of objects you can issue the delete operation.

More specifically:.
