如何从python中的不同目录导入函数

Question

我有以下文件结构：

/usr/share/pyshared/orca/scripts/toolkits/Gecko/script.py

在此文件中， def getExtents是我必须在以下文件中访问的函数： /usr/share/pyshared/orca/scripts/default.py

所以我想将功能从script.py导入以下文件：

/usr/share/pyshared/orca/scripts/default.py

在/usr/share/pyshared/orca/scripts/default.py添加了以下行：

from orca.scripts.toolkits.Gecko.script import getExtents

但是我收到以下错误：

 File "<string>", line 1, in <module>
  File "/usr/lib/pymodules/python2.7/orca/orca.py", line 1498, in main
    init(pyatspi.Registry)
  File "/usr/lib/pymodules/python2.7/orca/orca.py", line 1215, in init
    loadUserSettings()
  File "/usr/lib/pymodules/python2.7/orca/orca.py", line 837, in loadUserSettings
    _scriptManager.activate()
  File "/usr/lib/pymodules/python2.7/orca/script_manager.py", line 80, in activate
    self.setActiveScript(self.getScript(None), "activate")
  File "/usr/lib/pymodules/python2.7/orca/script_manager.py", line 247, in getScript
    appScript = self.getDefaultScript()
  File "/usr/lib/pymodules/python2.7/orca/script_manager.py", line 214, in getDefaultScript
    import scripts.default as default
  File "/usr/lib/pymodules/python2.7/orca/scripts/default.py", line 57, in <module>
    from orca.scripts.toolkits.Gecko.script import getExtents
  File "/usr/lib/pymodules/python2.7/orca/scripts/toolkits/Gecko/__init__.py", line 1, in <module>
    from script import Script
  File "/usr/lib/pymodules/python2.7/orca/scripts/toolkits/Gecko/script.py", line 52, in <module>
    import orca.scripts.default as default
AttributeError: 'module' object has no attribute 'default'

Answer 1

我想你可能需要

from orca.scripts import default

另外，如评论中所述，检查是否具有相关的__init__.py

编辑 ：重新读取stacktrace，看起来您也有循环导入，您正在尝试在“ /usr/lib/pymodules/python2.7/orca/scripts/”的第52行中导入orca.scripts.default。工具包/Gecko/script.py”
