Re: How to pass parameter when importing a module?
Take a look at wxPython versioning: http://wiki.wxpython.org/index.cgi/MultiVersionInstalls The most simple usage looks like import wxversion wxversion.select("2.4") import wx Serge. This is essentially my second method: using another module to set parameter for myModule. Since wxPython uses this method, I suppose this is the standard approach for this problem. Thanks.

How to pass parameter when importing a module?
Dear list, What I would like to do is something like: In myModule.py ( a wrapper module for different versions of the module), if lib == 'standard': from myModule_std import * elsif lib == 'optimized' from myModule_op import * but I do not know how to pass variable lib to myModule.py to achieve the following effect: >>> lib = 'standard' >>> from myModule import * # actually import myModule_std From what I have read, from does not take any parameter. Maybe I should use environmental variables? >>> os.putenv('lib', 'standard') >>> from myModule import * myModule.py - import os lib = os.getenv('lib') ... or use a separate module? param.py - para = {} def setParam(key, val): para[key] = val main session >>> import param >>> param.setParam('lib','standard') >>> from myModule import * in myModule.py -- from param import para try: lib = para['lib'] except: lib = 'standard' ... Is there an established approach for this problem? Many thanks in davance. Bo === FULL STORY: I have several modules all (SWIG) wrapped from the same C++ source code but with different compiling flags. For example, myModule_std (standard module) myModule_op (optimized, without error checking) ... These modules are put directly under /.../site-packages . To load a module, I use, for example from myModule_op import * This works fine until I need to write some helper functions for myModule_?? in another module myHelper.py since I do not know which myModule is being used from myModule?? import A,B I find one solution # find out which module is being used import sys if 'myModule_op' in sys.modules.keys(): from myModule_op import A,B else: from myModule_std import A,B but not completely satisfied. Therefore, I am writing a 'wrapper' module myModule that can load one of the myModule_?? modules according to user supplied info. -- http://mail.python.org/mailman/listinfo/python-list
