this&nbsp;module&nbsp;as&nbsp;os.path.&nbsp;&nbsp;The&nbsp;"os.path"&nbsp;name&nbsp;is&nbsp;an&nbsp;alias&nbsp;for&nbsp;this<br>
module&nbsp;on&nbsp;Posix&nbsp;systems;&nbsp;on&nbsp;other&nbsp;systems&nbsp;(e.g.&nbsp;Mac,&nbsp;Windows),<br>
os.path&nbsp;provides&nbsp;the&nbsp;same&nbsp;operations&nbsp;in&nbsp;a&nbsp;manner&nbsp;specific&nbsp;to&nbsp;that<br>
platform,&nbsp;and&nbsp;is&nbsp;an&nbsp;alias&nbsp;to&nbsp;another&nbsp;module&nbsp;(e.g.&nbsp;macpath,&nbsp;ntpath).<br>
&nbsp;<br>
Some&nbsp;of&nbsp;this&nbsp;can&nbsp;actually&nbsp;be&nbsp;useful&nbsp;on&nbsp;non-Posix&nbsp;systems&nbsp;too,&nbsp;e.g.<br>
