It’s reasonable, but we wanted to do better. So, we wrote a little Python 3 program that we use to put files into S3 buckets. If the bucket doesn’t yet exist, the program will create the bucket. Last but not least, we should include this line of code so that we can pause our code for a second so that we are not spamming the website with requests.
