Karthikeyan Singaravelan added the comment: Is there a way to test this or trigger this code using Python syntax? `slice(start, stop, step).indices()` uses slice_indices in Objects/sliceobject.c . I checked the function docs https://docs.python.org/2.7/c-api/slice.html#c.PySlice_GetIndices

Re: Cookies not showing up in environ

Yes, this was the problem. At some point early in my attempts I got the idea that linking up Django to a production web server required writing a separate wsgi.py script. Wrong. Replaced the wsgi.py with the default Django wsgi.py for the project and everything seems resolved. Thank you. --

Raymond Hettinger added the comment: Additional notes: * reversed() is preferred over the range(n-1, -1, -1) style both for clarity and speed. If reversed is slower, then it would be mean that something is sly wrong with range.__reversed__ which should be able to iterate backwards as

[issue33089] Add multi-dimensional Euclidean distance function to the math module

Serhiy Storchaka added the comment: I think we should guarantee some properties: 1. The result of hypot(x, y, z, ...) shouldn't depend on the order of arguments. 2. It should be monotonic for all arguments: hypot(..., x, ...) <= hypot(..., y, ...) for abs(x) < abs(y). 3. hypot(..., inf,
