The function readFolderContent ( ) used in the compute _ heart _ disease recipe includes these lines: with folder.get _ download _ stream ( names

The function readFolderContent() used in the compute_heart_disease recipe includes these lines:
with folder.get_download_stream(names_data) as stream:
text_data = stream.read()
Why is the code above preferable for reading data from a managed folder instead of a snippet like:
file_path = folder.get_path()+'/'+ 'heart-disease.names'
file_handle = open(file_path)
text_data = file_handle.readlines()
The second snippet is actually better.
Its fewer lines.
The second snippet will fail on a non-local filesystem (like S3 or HDFS).
Its streaming so guaranteed to be faster.
