Is there an elegant way to unget a line when reading from a file/stream iterator/generator?
By "unget" I mean a way to push back a line into the source stream and backtrack the iterator/generator one step? The only alternative I can see is to put my line reading in a while-True loop (vs. a for-loop) that manually calls my file/stream iterator/generator's .next() method while manually handling the StopIteration exception. Doesn't sound too elegant. Is there a Pythonic design pattern/best practice that I can apply here? Thank you, Malcolm -- http://mail.python.org/mailman/listinfo/python-list
