How can I upload a file in S3 bucket using boto in Python?

Ex: I have a bucket name = Text. And in the bucket, I have 2 folders named "input" & "output". Now I want to copy a file from the local directory to S3 "dump" folder using python. Can anyone help me?

You can use method of creating object instance to upload the file from your local machine to AWS S3 bucket in Python using boto3 library.

Here is the code I used for doing this:

import boto3
s3 = boto3.resource('s3')
s3.create_bucket(Bucket= 'anikets3bucket')

Hope it helps!

perfect.Thank you

I am trying to upload a file inside the sub-folder. I tried something like 


It does not work. Suggestions please ...

What error are you getting?

    raise ParamValidationError(report=error_msg)
botocore.exceptions.ParamValidationError: Parameter validation failed:
Invalid bucket name "anikets3bucket/folder1

": Bucket name must match the regex "^[a-zA-Z0-9.\-_]{1,255}$"

Bucket names cannot have '/' in them. When you use a url like this "anikets3bucket/folder1" the tool simply treats the parts behind / as "directory".

Check your bucket name properly.
Perfect! Helped a lot!
