def deleteDir( dir ):
 for name in os.listdir( dir ):
 file = dir + "/" + name
 if not os.path.isfile( file ) and os.path.isdir( file ):
 deleteDir( file ) # It's another directory - recurse in to it...
 else:
 os.remove( file ) # It's a file - remove it...
 os.rmdir( dir )

# Script entry point...
#--------------------------------------
# Creating a new directory is easy...
os.mkdir( "test_dir" )
# Pause for a moment so we can actually see the directory get created.
input( 'A directory called "tes_dir" was created.

Press Enter to delete it.' )
# Deleting it can be a little harder since it may contain files, so we'll need 
# to write a function to help us out here.
deleteDir( "test_dir" );
