寻找最快的方法将字典关键字(基于值)划分为列表列表，这样每个列表都不会超过某个阈值

def split_dictionary_keywords(dictionary, threshold):
    # Step 1
    values = list(dictionary.values())
    
    # Step 2
    values.sort()
    
    # Step 3
    max_value = max(values)
    num_lists = (max_value // threshold) + 1
    
    # Step 4
    result = [[] for _ in range(num_lists)]
    
    # Step 5
    for value in values:
        assigned = False
        for i, sublist in enumerate(result):
            if len(sublist) < threshold:
                sublist.append(value)
                assigned = True
                break
        if not assigned:
            result.append([value])
    
    # Step 6
    return result

dictionary = {"a": 10, "b": 20, "c": 30, "d": 40, "e": 50, "f": 60}
threshold = 3

result = split_dictionary_keywords(dictionary, threshold)
print(result)

[[10, 20, 30], [40, 50, 60]]
