📄 MockRequest.is_unverifiable() in src/requests/cookies.py

📈 Performance improved by 5% (0.05x faster)

⏱️ Runtime went down from 50.5 microseconds to 47.9 microseconds (best of 88 runs)

Explanation and details

Certainly! Here is an optimized version of your program.

Changes made.

  1. Replaced urlparse with a regex match using the re module for a more efficient extraction of the scheme.
  2. Used a staticmethod to define the _get_scheme method for clarity and encapsulation of the scheme extraction logic.

Correctness verification

The new optimized code was tested for correctness. The results are listed below.
