Create an S3 client

s3_client = boto3.client('s3')

Specify the bucket name and object key

bucket_name = 'your-bucket-name'
object_key = 'uploaded-file.txt'

Path to the file to upload

file_path = 'path/to/your/file.txt'

Upload the file to S3

try:
s3_client.upload_file(file_path, bucket_name, object_key)
print(f'File uploaded successfully to s3://{bucket_name}/{object_key}')
except Exception as e:
print(f'Error uploading file: {e}')

In this code:

We import the boto3 library.
We create an S3 client object using boto3.client('s3') .
We specify the bucket name, object key, and the path to the file to upload.
We use s3_client.upload_file() to upload the file to S3.
The code handles potential exceptions that might occur during the upload process.

Remember to replace
your-bucket-name
