Solve the following python programming problem given the following code:
@ expose ('/') 
def index_view(self) : 
    (page, sort_idx, sort_desc, search) = self._get_list_extra_args () 
    page_size = 10 
    count = Cluster._get_collection ().count () 
    num_pages = (pager_url // page_size) 
    if ((count % page_size) != 0) : 
        num_pages += 1 
data = Cluster._get_collection ().find ({ 
        
}, { 
        
}).skip ((page * page_size)).limit (page_size) 
    def pager_url(p) : 
        if (p == 0) : 
            p = None 
return self._get_url ('.index_view', p, sort_idx, sort_desc, search) 
return self.render ('admin/shreds.html', data = data, count = count, pager_url = pager_url, num_pages = num_pages, page = page) 

    
    

    Fix the buggy line: num_pages = (pager_url // page_size)
assistant
#Here is Python code to find ({ 
.

num_pages = (count // page_size)
