97bd48c0 - Improve range: refactor, support start as an optional kwarg, clearer docs and error messages (#38041)

Improve range: refactor, support start as an optional kwarg, clearer docs and error messages (#38041) Mathematically a range is uniquely determined by three out of four of start, step, stop, length. Furthermore if one assumes step=1 any combination of two others macthematically suffices to specify a range. With this PR the range function reflects this. Any combination of three (two non step) arguments will be accepted.
