python boto3 upload file to s3

Certainly! Below is an informative tutorial on how to use Python's Boto3 library to upload a file to Amazon S3 (Simple Storage Service). Make sure you have the Boto3 library installed before proceeding. You can install it using:
Now, let's create a Python script with the following code to upload a file to an S3 bucket:
Here's a breakdown of the script:
Import Boto3 and NoCredentialsError: Import the boto3 library for working with AWS services, and specifically, the NoCredentialsError class for handling authentication errors.
Define the upload_to_s3 function: This function takes three parameters - the local file path (local_file_path), the name of the S3 bucket (bucket_name), and the desired name for the file on S3 (s3_file_name).
Create an S3 client: Initialize a Boto3 S3 client.
Try to upload the file: Attempt to upload the local file to the specified S3 bucket with the given S3 filename.
Handle exceptions: Catch FileNotFoundError if the local file is not found, and catch NoCredentialsError if AWS credentials are not available.
Replace placeholder values: Replace local_file_path, bucket_name, and s3_file_name with your actual local file path, S3 bucket name, and desired S3 file name.
Run the script: Execute the script, and it will upload the specified file to the specified S3 bucket.
Remember to configure your AWS credentials using the AWS CLI or by setting environment variables. Ensure that the IAM user associated with the credentials has the necessary permissions to upload files to the specified S3 bucket.
