⚡️ Speed up method _NumberRangeBase._describe_range by 5%

[codeflash-ai]

📄 5% (0.05x) speedup for _NumberRangeBase._describe_range in src/click/types.py

⏱️ Runtime : 83.9 microseconds → 79.9 microseconds (best of 50 runs)

📝 Explanation and details

To optimize this program for faster execution, we can implement the following changes.

1. Use is for None checks since it is slightly faster than ==.
2. Use an f-string directly in the _describe_range method instead of storing the result in intermediate variables.
3. We will go ahead and refactor parts of the code to ensure the method calls and attribute accesses are minimized.

Here's the optimized version of the program.

Explanation of Changes.

1. init method: No change necessary since it already seems optimal.
2. repr method: Directly integrated the clamp check within the f-string.
3. _describe_range method: Combined f-strings to directly return the result, avoiding intermediate variables and reducing the number of operations. Used is for None comparisons, which are faster.
