python - python 2.7.6至2.7.12破坏了我的脚本

Question

我正在使用一个简单的脚本将数据发送到elasticsearch节点，但是在更改python版本后，该脚本不再运行。它说错误在第6行，但我不知道为什么。我尝试在"is"后添加逗号，但没有效果。我试过将括号和括号下移，但它必须生效。 (为简便起见，我省略了import和其他定义的变量)

if "Temporary failure in name resolution" or "Timeout" in output:
            es.index(index='data', doc_type='data', body={
            'macs' : '',
            'data' : line,
            'date' : datetime.now(),
            'down' : 'yes' })

错误如下:

    snmpwalk: Timeout

Traceback (most recent call last):
  File "script.py", line 6, in <module>
    'down' : 'yes' })
  File "build/bdist.linux-x86_64/egg/elasticsearch/client/utils.py", line 69, in _wrapped

谢谢

这可能是网络问题，也可能是 Elasticsearch 的mmapfs目录已用尽。

尝试运行以下命令重新启动网络服务器

sudo service network-manager restart

如果它不起作用，则通过运行此命令来更改您的mmap计数

sudo sysctl -w vm.max_map_count=262144
