Boto3/S3: Renaming an object using copy_object

I'm trying to rename a file in my s3 bucket using python boto3, I couldn't clearly understand the arguments. can someone help me here?

What I'm planing is to copy object to a new object, and then delete the actual object.

I found similar questions here, but I need a solution using boto3.

I found another solution

    s3 = boto3.resource('s3')
    s3.Object('my_bucket','new_file_key').copy_from(CopySource='my_bucket/old_file_key')
    s3.Object('my_bucket','old_file_key').delete()
