AWS S3 with Python

In this example we will see the basic operations that we can do with the cube and the files

Installation

pip install boto3

Connection

from boto3 import client
from os import getenv

clientS3 = client("s3",
                  aws_access_key_id=getenv("AWS_ACCESS_KEY_ID"),
                  aws_secret_access_key=getenv("AWS_SECRET_ACCESS_KEY"),
                  region_name=getenv("REGION_NAME")
                  )

Methods for buckets

Create bucket

from botocore.exceptions import ClientError

def create_bucket(bucket: str):
    try:
        response = clientS3.create_bucket(Bucket=bucket)
        return response
    except ClientError as e:
        return e.response["Error"]

Delete bucket

from botocore.exceptions import ClientError

def delete_bucket(bucket: str):
    try:
        response = clientS3.delete_bucket(Bucket=bucket)
        return response
    except ClientError as e:
        return e.response["Error"]

List all buckets

from botocore.exceptions import ClientError

def list_buckets():
    try:
        response = clientS3.list_buckets()
        return response
    except ClientError as e:
        return e.response["Error"]

Methods for files

Upload file

from typing import BinaryIO
from botocore.exceptions import ClientError

def upload_file(data: BinaryIO, bucket: str, filename: str):
    try:
        clientS3.upload_fileobj(Fileobj=data, Bucket=bucket, Key=filename)
        return "success"
    except ClientError as e:
        return e.response["Error"]

Get file

from typing import BinaryIO
from botocore.exceptions import ClientError

def get_file(bucket: str, filename: str):
    try:
        response = clientS3.get_object(Bucket=bucket, Key=filename)
        return response
    except ClientError as e:
        return e.response["Error"]

Delete file

from typing import BinaryIO
from botocore.exceptions import ClientError

def delete_file(bucket: str, filename: str):
    try:
        response = clientS3.delete_object(Bucket=bucket, Key=filename)
        return response
    except ClientError as e:
        return e.response["Error"]
