I have something that seems to me has a bit more order:

import boto3
from pprint import pprint
from botocore.exceptions import NoCredentialsError


class S3(object):
    BUCKET = "test"
    connection = None

    def __init__(self):
        try:
            vars = get_s3_credentials("aws")
            self.connection = boto3.resource('s3', 'aws_access_key_id',
                                             'aws_secret_access_key')
        except(Exception) as error:
            print(error)
            self.connection = None


    def upload_file(self, file_to_upload_path, file_name):
        if file_to_upload is None or file_name is None: return False
        try:
            pprint(file_to_upload)
            file_name = "your-folder-inside-s3/{0}".format(file_name)
            self.connection.Bucket(self.BUCKET).upload_file(file_to_upload_path, 
                                                                      file_name)
            print("Upload Successful")
            return True

        except FileNotFoundError:
            print("The file was not found")
            return False

        except NoCredentialsError:
            print("Credentials not available")
            return False

There're three important variables here, the BUCKET const, the file_to_upload and the file_name

BUCKET: is the name of your S3 bucket

file_to_upload_path: must be the path from file you want to upload

file_name: is the resulting file and path in your bucket (this is where you add folders or what ever)

There's many ways but you can reuse this code in another script like this

import S3

def some_function():
    S3.S3().upload_file(path_to_file, final_file_name)

You should mention the content type as well to omit the file accessing issue  import os image  fly png  s3 filestore path    images fly png  filename  file extension   os path splitext image  content type dict   quot  png quot   quot image png quot   quot  html quot   quot text html quot                   quot  css quot   quot text css quot   quot  js quot   quot application javascript quot                   quot  jpg quot   quot image png quot   quot  gif quot   quot image gif quot                   quot  jpeg quot   quot image jpeg quot    content type content type dict file extension  s3   boto3 client  s3   config boto3 session Config signature version  s3v4                      region name  ap-south-1                     aws access key id S3 KEY                    aws secret access key S3 SECRET  s3 put object Body image  Bucket S3 BUCKET  Key s3 filestore path  ContentType content type

Try this     import boto import boto s3 import sys from boto s3 key import Key  AWS ACCESS KEY ID      AWS SECRET ACCESS KEY       bucket name   AWS ACCESS KEY ID lower      -dump  conn   boto connect s3 AWS ACCESS KEY ID          AWS SECRET ACCESS KEY    bucket   conn create bucket bucket name      location boto s3 connection Location DEFAULT   testfile    replace this with an actual filename  print  Uploading  s to Amazon S3 bucket  s          testfile  bucket name   def percent cb complete  total       sys stdout write          sys stdout flush     k   Key bucket  k key    my test file  k set contents from filename testfile      cb percent cb  num cb 10     UPDATE  I am not a pythonist  so thanks for the heads up about the import statements  Also  I d not recommend placing credentials inside your own source code  If you are running this inside AWS use IAM Credentials with Instance Profiles  http   docs aws amazon com IAM latest UserGuide id roles use switch-role-ec2 instance-profiles html   and to keep the same behaviour in your Dev Test environment  use something like Hologram from AdRoll  https   github com AdRoll hologram

If you have the aws command line interface installed on your system you can make use of pythons subprocess library  For example  import subprocess def copy file to s3 source  str  target  str  bucket  str      subprocess run   quot aws quot    quot s3 quot     quot cp quot   source  f quot s3    bucket   target  quot     Similarly you can use that logics for all sort of AWS client operations like downloading or listing files etc  It is also possible to get return values  This way there is no need to import boto3  I guess its use is not intended that way but in practice I find it quite convenient that way  This way you also get the status of the upload displayed in your console - for example  Completed 3 5 GiB 3 5 GiB  242 8 MiB s  with 1 file s  remaining  To modify the method to your wishes I recommend having a look into the subprocess reference as well as to the AWS Cli reference  Note  This is a copy of my answer to a similar question

This is a three liner  Just follow the instructions on the boto3 documentation   import boto3 s3   boto3 resource service name    s3   s3 meta client upload file Filename    C  foo bar baz filetype   Bucket    yourbucketname   Key    baz filetype     Some important arguments are  Parameters  Filename  str  -- The path to the file to upload  Bucket  str  -- The name of the bucket to upload to  Key  str  -- The name of the that you want to assign to your file in your s3 bucket  This could be the same as the name of the file or a different name of your choice but the filetype should remain the same   Note  I assume that you have saved your credentials in a    aws folder as suggested in the best configuration practices in the boto3 documentation
