content from one category

I'm trying to get content from one category to show giving ten results can anyone help to get this working? I'm getting an error on line 3 :

<?php global $post; 
  $args = array(
  'numberposts' => [10]
 'category' => [uncategorised]
);
$posts = get_posts()
foreach($posts as $post){
    setup_postdata($post);}
    ?>
    <div id="art-av">
	<div id="av-side-l">
	<div id="av"><?php if ( has_post_thumbnail() ) { /* loades the post's featured thumbnail, requires Wordpress 3.0+ */ echo '<div class="featured-thumbnail">'; the_post_thumbnail(); echo '</div>'; } ?>
</div>
	<div id="date-av"><?php the_time('F j, Y'); ?></div>
	<div id="com-av"><?php comments_popup_link('No Comments', '1 Comment', '% Comments'); ?></div>
</div>
	<div id="av-side-r">
	<div id="tit-av"><a href="<?php the_permalink() ?>" class="blue" title="<?php the_title(); ?>" rel="bookmark"><?php the_title(); ?></a></div>
	<div id="dec-av">
	<?php the_excerpt(); ?>
    </div>
</div>
</div>
<?php endforeach; ?>
