如何根据重复行数提取数据？

def extract_data(file_path, duplicate_count):
    data_dict = {}
    
    # 读取文件并统计每行数据的出现次数
    with open(file_path, 'r') as file:
        for line in file:
            line = line.strip()  # 去除行尾的换行符等空白字符
            if line in data_dict:
                data_dict[line] += 1
            else:
                data_dict[line] = 1
    
    # 提取出现次数大于等于指定重复行数的数据
    extracted_data = []
    for line, count in data_dict.items():
        if count >= duplicate_count:
            extracted_data.append(line)
    
    return extracted_data

# 示例用法
file_path = 'data.txt'  # 替换为实际的文件路径
duplicate_count = 3  # 替换为实际的重复行数
result = extract_data(file_path, duplicate_count)
print(result)
