Solve the following python programming problem given the following code:
def register_seq_blocks(model) : 
    all_models = [] 
    def create_model_list(current) : 
        all_models.append (current) 
        for m in current.get_submodules () : 
            create_model_list (m) 
create_model_list (model) 
    sequential_blocks = [] 
    for i in all_models : 
        for func in (i.get_tick_blocks () + i.get_posedge_clk_blocks ()) : 
            (tree, src) = get_method_ast (func) 
            DetectIncorrectValueNext (func, 'value').visit (tree) 
            DetectMissingValueNext (func, 'next').visit (tree) 
            if ('tick_fl' in DetectDecorators ().enter (tree)) : 
                func = _pausable_tick (func) 
sequential_blocks.append (func) 
for func in i.get_combinational_blocks () : 
            (tree, _) = get_method_ast (_) 
            DetectIncorrectValueNext (func, 'next').visit (tree) 
            DetectMissingValueNext (func, 'value').visit (tree) 
return sequential_blocks 

    
    

    Fix the buggy line: (tree, _) = get_method_ast (_)
assistant
#Here is Python code to fix the buggy line: (tree, _) = get_method_ast (_)
.

(tree, _) = get_method_ast (func)
