   src = open( file_path ).read()
   
   # from file
   print parser.load( 'file_path' )
   
   # from string
   print parser.parse( 'src' )
   
   # Create parser object
   p = parser.Stylesheet( options=dict( compress=True ) )
   print p.loads( src )
   p.load( file_path )
   print p

Changes

Make sure you`ve read the following document if you are upgrading from previous versions of scss:

http://packages.python.org/scss/changes.html

Examples

1. Nested Rules

   Example:

   .selector {
       a {
           display: block;
       }
       strong {
           color: blue;
       }
   }

   …produces:

   .selector a {
       display: block}
   
   .selector strong {
       color: blue}

2. Variables

   Example:

   $main-color: #ce4dd6;
   $style: solid;
   $side: bottom;
   #navbar {
       border-#{$side}: {
       color: $main-color;
       style: $style;
       }
   }

   …produces:

   #navbar {
       border-bottom-color: #ce4dd6;
       border-bottom-style: solid}

3. Mixins

   Example:

   @mixin rounded($side, $radius: 10px) {
       border-#{$side}-radius: $radius;
       -moz-border-radius-#{$side}: $radius;
       -webkit-border-#{$side}-radius: $radius;
   }
   #navbar li { @include rounded(top); }
   #footer { @include rounded(top, 5px); }
   #sidebar { @include rounded(left, 8px); }

   …produces:

   #navbar li {
           -moz-border-radius-top: 10px;
           -webkit-border-top-radius: 10px;
           border-top-radius: 10px}
   
   #footer {
           -moz-border-radius-top: 5px;
           -webkit-border-top-radius: 5px;
           border-top-radius: 5px}
   
   #sidebar {
           -moz-border-radius-left: 8px;
           -webkit-border-left-radius: 8px;
           border-left-radius: 8px}

4. Extend (using @extend)

   Example:

   .error {
       border: 1px #f00;
       background-color: #fdd;
   }
   .error.intrusion {
       background-image: url("/image/hacked.png");
   }
   .seriousError {
       @extend .error;
       border-width: 3px;
   }

   …produces:

   .error, .seriousError {
       background-color: #fdd;
       border: 1px #f00}
   
   .error .intrusion, .seriousError .intrusion {
       background-image: url('/image/hacked.png')}
   
   .seriousError {
       border-width: 3px}

5. Interactive mode

   Example:

   $ python scss.py --interactive
   >>> 25px + 1.5em
   44.5px
   >>> lighten(rgba(130,130,130,.4),10%)
   rgba(155,155,155,0.40)
   >>> .rule { test: red; }
   .rule {
       test: red }
   >>> _
