⚡️ Speed up method SessionRedirectMixin.get_redirect_target by 19%

[codeflash-ai]

📄 19% (0.19x) speedup for SessionRedirectMixin.get_redirect_target in src/requests/sessions.py

⏱️ Runtime : 19.2 microseconds → 16.2 microseconds (best of 71 runs)

📝 Explanation and details

Certainly! Here's an optimized version of the given Python program.

Changes made.

1. Avoid Unnecessary Function Calls.

   • In get_redirect_target, instead of calling to_native_string, directly converting the encoding by chaining .encode("latin1").decode("utf8").

2. Simplified Conditional Checks.

   • Simplified the return statements in the to_native_string function for clarity.

By making these changes, we have reduced the overhead caused by unnecessary function calls without altering the functionality. This should lead to a slight improvement in the program's performance.
