Solve the following python programming problem given the following code:
@ web.authenticated 
def get(self) : 
    app = self.application 
    draw = self.get_argument ('draw', type = int) 
    start = self.get_argument ('start', type = int) 
    length = self.get_argument ('length', type = int) 
    search = self.get_argument ('search[value]', type = str) 
    column = self.get_argument ('order[0][column]', type = int) 
    sort_by = self.get_argument (('columns[%s][data]' % column), type = str) 
    sort_order = (self.get_argument ('order[0][dir]', type = str) == 'asc') 
    def key(item) : 
        val = getattr (item [1], sort_by) 
        if (sys.version_info [0] == 3) : 
            val = str (val) 
return val 
tasks = sorted (iter_tasks (_.events, search = search), key = key, reverse = sort_order) 
    tasks = list (map (self.format_task, tasks)) 
    filtered_tasks = [] 
    i = 0 
    for (_, task) in tasks : 
        if (i < start) : 
            i += 1 
            continue 
if (i >= (start + length)) : 
            break 
task = as_dict (task) 
        if task ['worker'] : 
            task ['worker'] = task ['worker'].hostname 
filtered_tasks.append (task) 
        i += 1 
self.write (dict (draw = draw, data = filtered_tasks, recordsTotal = len (tasks), recordsFiltered = len (tasks))) 

    
    

    Fix the buggy line: tasks = sorted (iter_tasks (_.events, search = search), key = key, reverse = sort_order)

#Here is Python program to fix the buggy line: tasks = sorted (iter_tasks (_.
