Here’s a faster and slightly more memory-efficient version of your function. This version iterates only once over the environment and only picks out keys of interest, avoiding extra dictionary lookups and skips unconditional continues by restructuring control-flow. **Optimizations explained:** - Access `os.environ` only once, reducing attribute lookups. - Use `try/except KeyError` for key fetch to avoid repeated dictionary lookups (faster than `in` or `.get()` when most keys exist). - Minor: Removed explicit type annotation on the local variable, which speeds up runtime slightly (though the function signature type remains). Functionality and comments are preserved.
