   import boto3
   
   def lambda_handler(event, context):
       # Specify the S3 bucket name
       s3_bucket = ""
   
       # Specify the new blank file key
       new_file_key = "blank_file.txt"
   
       # Initialize the S3 client
       s3_client = boto3.client('s3')
   
       # Create a blank text file content
       blank_content = ''
   
       try:
           # Put the blank text file into the specified S3 bucket
           s3_client.put_object(Body=blank_content, Bucket=s3_bucket, Key=new_file_key)
   
           print(f"Blank file created: s3://{s3_bucket}/{new_file_key}")
   
           return {
               'statusCode': 200,
               'body': 'Blank file creation complete!'
           }
   
       except Exception as e:
           print(f"Error: {str(e)}")
           return {
               'statusCode': 500,
               'body': 'Error creating blank file'
           }
