title: How to fetch all items of a particular Attribute from an AWS DynamoDB Table using Python boto3?
body: <p>I am pretty new to AWS Dynamodb. I am using python's boto3 to fetch all items of a particular attribute (say, Attribute name is 'Name') from the dynamodb table. </p>
  
  <p>Although there are other attributes too in the table like 'Email', 'Profession'.  I need to fetch or get all items only of the attribute 'Name'. My Name attribute consists of four items :
  Nick, John, Gary, Jules. 
  How can I fetch this using boto3 ? I tried with client.query method of boto3 but I am not sure if it works. </p>
