Solve the following python programming problem given the following code:
def get_fptree(transactions, key_func = None, min_support = 2) : 
    'Given a list of transactions and a key function, returns a data
       structure used as the input of the relim algorithm.

       :param transactions: a sequence of sequences. [[transaction items...]]
       :param key_func: a function that returns a comparable key for a
        transaction item.
       :param min_support: minimum support.
    ' 
    if (key_func is None) : 
        def key_func(e) : 
            return e 
(asorted_seqs, frequencies) = _sort_transactions_by_freq (transactions, key_func, True, False, False) 
    transactions = [[item [1] for item in aseq if (item [0] >= min_support)] for aseq in new_heads] 
    root = FPNode (FPNode.root_key, None) 
    heads = { 
        
} 
    last_insert = { 
        
} 
    for transaction in transactions : 
        root.add_path (transaction, 0, len (transaction), heads, last_insert) 
sorted_heads = sorted (heads.values (), key = (lambda v : (v [1], v [0].key))) 
    new_heads = OrderedDict () 
    for (head, head_support) in sorted_heads : 
        new_heads [head.key] = (head, head_support) 
return (root, new_heads) 

    
    

    Fix the buggy line: transactions = [[item [1] for item in aseq if (item [0] >= min_support)] for aseq in new_heads]
assistant
#Here is Python code to fix the buggy line: transactions = [[item [1] for item in aseq if (item [0] >= min_support)] for aseq in new_heads]
.

transactions = [[item [1] for item in aseq if (item [0] >= min_support)] for aseq in asorted_seqs]
