Thanks all. Another question: I have to open file for writing ('wb') but I noticed that both tempfile.mkstemp() and os.fdopen() accept a "mode" argument. It's not clear *when* do I have to specify such mode. When using tempfile.mkstemp?
>>> fileno, name = tempfile.mkstemp(text=False) >>> fd = os.fdopen(fileno) ...or when using os.fdopen()? >>> fileno, name = tempfile.mkstemp() >>> fd = os.fdopen(fileno, mode='wb') Moreover, what happens if I specify "text" mode when using mkstemp and "binary" mode when using fdopen? >>> fileno, name = tempfile.mkstemp(text=True) >>> fd = os.fdopen(fileno, 'wb') PS - I think that tempfile.mkstemp docstring should be enhanced to cover such and other questions (e.g. I find reasonable that every user using tempfile.mkstemp() should use also os.fdopen() in conjunction but this isn't mentioned). -- http://mail.python.org/mailman/listinfo/python-list
