Python为语法

Question

我是编程python的新手。我在Linux上建立了Beremiz程序，我得到了这个错误。

File "Beremiz.py", line 164, in <module> 
    from ProjectController import ProjectController, MATIEC_ERROR_MODEL, ITEM_CONFNODE 
    File "/DATA1/UTILITY/Beremiz/beremiz/ProjectController.py", line 16, in <module> 
    import connectors 
    File "/DATA1/UTILITY/Beremiz/beremiz/connectors/__init__.py", line 34 
    for name in listdir(_base_path) 
    ^


connectors = {name:_GetLocalConnectorClassFactory(name) 
        for name in listdir(_base_path) 
         if path.isdir(path.join(_base_path, name)) 
          and not name.startswith("__")} 

此语法不是python的构建。什么是问题？ 谢谢大家。

Answer 1

您需要确保您的Python版本支持字典理解语法。这需要Python> = 2.7或Python> = 3

否则，你可以修改这样的代码：

connectors = dict((name, _GetLocalConnectorClassFactory(name)) 
        for name in listdir(_base_path) 
         if path.isdir(path.join(_base_path, name)) 
          and not name.startswith("__"))
