As you can see above the boto3 library got loaded successfully and the version is 1. This is as of Late so this may be different in your system based on when you install it. The first thing we need to do is click on create bucket and just fill in the details as shown below.
For now these options are not very important we just want to get started and programmatically interact with our setup. For now you can leave the rest of the options default for example for me the following settings were default at the time of this writing:. Once you verify that go ahead and create your first bucket. For me this looks something like this:. Now that we have our bucket created we need to proceed further into setting up a way to interact with it programmatically.
Those are necessary for the platform to know you are authorized to perform actions in a programmatic way rather than logging in the web interface and accessing the features via the console. So our next task is to find where and how those keys are configured and what is needed to set them up on our local computer to start talking to Amazon AWS S3. First we need to talk about how to add an AWS user.
If you do not have a user setup with AWS S3 full permissions then I will walk you through on how to get this done in a simple step by step guide. In the next steps you can use the defaults except the part that is asking you to set the permissions.
In this tab you want to expand below and type in the search S3. Once you do that a bunch of permissions will be loaded for you to select from, for now you can simply select the Full permissions for S3 as shown in the screenshot below.
You can skip the tags and proceed to add the user, the final screen summary should look like this. The final confirmation screen should show you the access key and the secret key. You want to save those for your reference as we would be using them in our code later. This screen looks something like this:. Do note I redacted my access and secret key from the screenshot for obvious reasons but you should have them if everything worked successfully.
Now that we have an access and secret key and our environment setup we can start writing some code. Before we jump into writing code that downloads uploads and lists files from our AWS bucket we need to write a simple wrapper that will be re-used across our applications that does some boiler plate code for the boto3 library.
One thing to understand here is that AWS uses sessions. Similar to when you login to the web console a session is initiated with a cookie and everything in a similar way this can be done programmatically.

In the above example the bucket sample-data contains an folder called a which contains foo. I know how to download a single file. For instance if i wanted foo.
However i am wondering if i can download the folder called a and all it's contents entirely? Any help would be appreciated. You list all the objects in the folder you want to download. Then iterate file by file and download it. The response is of type dict. The key that contains the list of the file names is "Contents". How are we doing? Please help us improve Stack Overflow.

Boto3 looks at various configuration locations until it finds the configuration values such as settings. If you do not want to create a session and access the resource, you can create an s3 client directly by using the following command.
Use the below script to download a single file from S3 using Boto3 Resource. Create necessary sub directories to avoid file replacements if there are one or more files existing in different sub buckets. Then download the file actually.
