在字典键中查找最大重复值

def find_max_duplicate_key(dictionary):
    keys = list(dictionary.keys())
    key_counts = {}
    
    # 计算每个键的出现次数
    for key in keys:
        if key in key_counts:
            key_counts[key] += 1
        else:
            key_counts[key] = 1
    
    max_count = max(key_counts.values())
    
    # 找到具有最大重复值的键
    max_duplicate_keys = [key for key, count in key_counts.items() if count == max_count]
    
    return max_duplicate_keys

# 示例用法
my_dict = {'a': 1, 'b': 2, 'c': 2, 'd': 3, 'e': 3, 'f': 3}
result = find_max_duplicate_key(my_dict)
print("具有最大重复值的键：", result)
