Python code to upload all files, containing defined extension, into AWS S3 using boto3 and os.walker

upload_file_to_s3.py

import os
import logging
import boto3
from botocore.exceptions import ClientError


path = '/home/{your user}/Documents'

def upload_file(file_name, bucket, object_name=None):
   
    if object_name is None:
        object_name = file_name

    s3_client = boto3.client('s3')
    try:
        response = s3_client.upload_file(file_name, bucket, object_name)
    except ClientError as e:
        logging.error(e)
        return False
    return True

# r=root, d=directories, f = files
for r, d, f in os.walk(path):
    for file in f:
        if '.docx' in file:
            upload_file(os.path.join(r, file), 'bucketname', file)
        elif '.png' in file:
            upload_file(os.path.join(r, file), 'bucketname', file)
        else:
            print('select file contains no docx or png extension')

   

To make it work, you need to install and set up AWS CLI - pip install awscli (https://aws.amazon.com/cli/) and you also need to install boto3 - pip install boto3 (https://boto3.amazonaws.com/v1/documentation/api/latest/guide/quickstart.html).
