Solve the following python programming problem given the following code:
def __init__(self, klass_info, select, db) : 
    self.db = db 
    select_fields = klass_info ['select_fields'] 
    from_parent = klass_info ['from_parent'] 
    if (not from_parent) : 
        self.cols_start = select_fields [0] 
        self.cols_end = (select_fields [(- 1)] + 1) 
        self.init_list = [f [0].target.attname for f in select [self.cols_start : self.cols_end]] 
        self.reorder_for_init = None 
else : 
        model_init_attnames = [f.attname for f in klass_info ['model']._meta.concrete_fields] 
        reorder_map = [] 
        for idx in select_fields : 
            field = select [idx] [0].target 
            init_pos = model_init_attnames.index (field.attname) 
            reorder_map.append ((init_pos, field.attname, idx)) 
reorder_map.sort () 
        self.init_list = [v [1] for v in select_fields] 
        pos_list = [row_pos for (_, _, row_pos) in reorder_map] 
        def reorder_for_init(row) : 
            return [row [row_pos] for row_pos in pos_list] 
self.reorder_for_init = reorder_for_init 
self.model_cls = self.get_deferred_cls (klass_info, self.init_list) 
    self.pk_idx = self.init_list.index (self.model_cls._meta.pk.attname) 
    self.related_populators = get_related_populators (klass_info, select, self.db) 
    field = klass_info ['field'] 
    reverse = klass_info ['reverse'] 
    self.reverse_cache_name = None 
    if reverse : 
        self.cache_name = field.remote_field.get_cache_name () 
        self.reverse_cache_name = field.get_cache_name () 
else : 
        self.cache_name = field.get_cache_name () 
        if field.unique : 
            self.reverse_cache_name = field.remote_field.get_cache_name () 

    
    

    Fix the buggy line: self.init_list = [v [1] for v in select_fields]

#Here is Python program to fix the buggy line: self.

self.init_list = [v [1] for v in reorder_map]
