Using AWS Q Developer in Python
Below is an example of AWS Q Developer generating a function to upload a file to Amazon S3:
import boto3

def upload_file_to_s3(bucket_name, file_path, object_name):
"""Uploads a file to an S3 bucket."""
s3 = boto3.client('s3')
try:
s3.upload_file(file_path, bucket_name, object_name)
print(f"File {file_path} uploaded to {bucket_name}/{object_name}")
except Exception as e:
print(f"Error uploading file: {e}")
upload_file_to_s3("my-bucket", "localfile.txt", "uploaded-file.txt")

AWS Q Developer can generate this function automatically from a
simple comment like:
