Set parameterized COM property

Getting a parameterized property (Ms Word's Options.DefaultFilePath) works fine:

In [117]: o
Out[117]: <win32com.gen_py.Microsoft Word 12.0 Object Library.Options instance at 0x43743792>

In [121]: o.DefaultFilePath(win32com.client.constants.wdDocumentsPath)
Out[121]: u'c:\\documents and settings\\user\\\u043c\u043e\u0438 \u0434\u043e\u043a\u0443\u043c\u0435\u043d\u0442\u044b\\\u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c\u0430 \u0434\u043b\u044f \u043f\u043e\u0432\u0435\u0440\u043a\u0438 \u0441\u0438'

But not setting:

In [122]: o.DefaultFilePath(win32com.client.constants.wdDocumentsPath)=".."
  File "<ipython-input-122-f2ed5d26c67c>", line 1
    o.DefaultFilePath(win32com.client.constants.wdDocumentsPath)=".."
SyntaxError: can't assign to function call

Also tried a suggested way from C# Late Binding for Parameterized Property :

In [123]: o.set_DefaultFilePath(win32com.client.constants.wdDocumentsPath,"..")
<...>
AttributeError: '<win32com.gen_py.Microsoft Word 12.0 Object Library.Options instance at 0x43743792>' object has no attribute 'set_DefaultFilePath'

Quick Start to Client side COM and Python also comes up empty.

Solution 
  • In [160]: dir(o)
Out[160]:
['CLSID',
 'DefaultFilePath',
 'SetDefaultFilePath',
 'SetWPHelpOptions',
 <...>

    Which suggests:

    o.SetDefaultFilePath(win32com.client.constants.wdDocumentsPath,u"..")
