Hi, I was trying to automatically doctest some of the examples in Numpy_Example_List_With_Doc and obtained a large number of whitespace errors. The tests, that I tried, passed after turning of whitespace checking in doctest. Later I saw that the original numpy example list has leading whitespace that, I think, gets removed by the script that generates the With_Doc page. I think on line 179 a right strip should be used instead of a strip(), so that any leading white space is kept: change `` line = line.strip()`` to ``line = line.rstrip()`` the new lines read: for i, line in enumerate(input_data): # look for optional anchor name line = line.rstrip() match = re_anchor.match(line) Looking briefly at the newly generated output, everything still seems to be correctly generated, but I haven't verified if everything is really correct.
