Bug description:
When calculating the stop
value of a range, the expectation is that it will calculate the value that will match the last element following the step
value. This is not the case as in the example below:
Python 3.13.5 (main, Jun 11 2025, 15:36:57) [Clang 17.0.0 (clang-1700.0.13.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> range(0, 98, 6)[6::5]
range(36, 102, 30)
>>> range(0, 98, 6)[6::5][0::]
range(36, 126, 30)
It is expected that the stop
value of range(0, 98, 6)[6::5]
to be 126, when it calculated to be 102. This does not affect the actual elements in the range, it is just unexpected.
