To optimize the runtime and memory usage of the given Python function, we can inline the `_alias_if_valid` function to avoid the overhead of additional function calls and reduce the redundancy. Here's the optimized version of the code. ### Explanation. 1. **Inlining `_alias_if_valid` Function:** By inlining the code of `_alias_if_valid` directly into `_field_name_for_signature`, we eliminate the overhead of multiple function calls and simplify the logic. 2. **Conditional Checks:** Add checks directly within the return statement to reduce unnecessary temporary variables. These changes should help in reducing the runtime and memory overhead of the function while maintaining the same functionality and returned values.
