Consistent use of valid index check · Issue #99761 · python/cpython (original) (raw)
Feature or enhancement
In listobject.c there is an optimization to check whether an index is valid (e.g. 0 <= index < N) using a single comparison. The same optimization is not used in other files such as tupleobject.c.
By replacing index checks with a single macro that includes the optimization we have consistency in the code and have the optimized check for all index checks.
