Lets get started

Before starting this article I hope you have AWS account and python installed in your machine that’s what we need to do this

To complete this task we need :

  1. ACCESS KEY (which can be found/created using IAM in AWS)

import os

import boto3

from botocore.exceptions import ClientError

ACCESS_KEY = ‘your_access_key’

SECRET_KEY = ‘your_secret_key’

bucket_name = ‘testingkit’

client_s3 = boto3.client(




file_path = os.path.join(os.getcwd(),)

for file in os.listdir(file_path):

if not file.startswith(‘~’):



os.path.join(file_path, file),bucket_name,file


except ClientError as CE:

print(‘invalid credentials ‘ + CE)

except Exception as e:


In this above code use your ACCESS KEY & SECRET KEY and it will upload your all the files from your present working directory to s3 Bucket to import files from machine I’ve Imported OS module,

and BOTO3 which is a AWS SDK which will help us to connect to s3 and upload our files from machine to Bucket, that’s what we want to do.
