⚡️ Speed up function select_proxy by 22%

[codeflash-ai]

📄 22% (0.22x) speedup for select_proxy in src/requests/utils.py

⏱️ Runtime : 1.02 millisecond → 829 microseconds (best of 21 runs)

📝 Explanation and details

Sure! Here is a more optimized version of the program.

Changes Made.

1. Import urlparse from urllib.parse instead of src.requests.compat for a more standard approach.
2. Removed the reassignment of proxies to itself with a default empty dictionary since we handle the if not proxies check earlier.
3. Instead of constructing a list and iterating over potentially multiple keys in a loop, use the or operator to check for each proxy key in a single statement, reducing overhead and making it faster.
4. Simplified by storing urlparts.hostname into hostname.

These changes help in reducing the complexity of the function and should result in a better overall performance.
