it = client.pull_log('project1', 'logstore1', from_time="2018-1-1 10:10:10", to_time="2018-1-1 10:20:10", file_path="/data/dump_{}.data")

res.log_print()
这里应该写错了，应该是 client.pull_log_dump 而不是 client.pull_log；
另外 pull_log_dump 中使用了进程池，例子中需要加 if __name__ == '__main__': ，不然会报错 concurrent.futures.process.BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending
而且似乎 pull_log_dump 的结果也是不可迭代的
