怎么样Python通过实现将颜色hex值转换成rgb？

function hex2rgb( $colour ) { 
  if ( $colour[0] == '#' ) { 
    $colour = substr( $colour, 1 ); 
  } 
  if ( strlen( $colour ) == 6 ) { 
    list( $r, $g, $b ) = array( $colour[0] . $colour[1], $colour[2] . $colour[3], $colour[4] . $colour[5] ); 
  } elseif ( strlen( $colour ) == 3 ) { 
    list( $r, $g, $b ) = array( $colour[0] . $colour[0], $colour[1] . $colour[1], $colour[2] . $colour[2] ); 
  } else { 
    return false; 
  } 
  $r = hexdec( $r ); 
  $g = hexdec( $g ); 
  $b = hexdec( $b ); 
  return array( 'red' => $r, 'green' => $g, 'blue' => $b ); 
} 
//测试 
var_dump(hex2rgb("#eeeeee"));

array(3) {
 ["red"]=>
 int(238)
 ["green"]=>
 int(238)
 ["blue"]=>
 int(238)
}
