⚡️ Speed up method ProgressBar.make_step by 11%

[codeflash-ai]

📄 11% (0.11x) speedup for ProgressBar.make_step in src/click/_termui_impl.py

⏱️ Runtime : 1.70 millisecond → 1.53 millisecond (best of 8 runs)

📝 Explanation and details

Here's a more optimized version of your ProgressBar class. The main focus of optimization has been removing redundant operations, using efficient data structures, and minimizing function calls where possible.

Changes made.

1. Moved the length hint logic directly into the constructor to avoid unnecessary calls.
2. Simplified the handling of the file parameter by combining checks and fallbacks.
3. Moved time.time() calls to variables to avoid calling the function repeatedly in the make_step method.
4. Changed the rolling average calculation to a list with a fixed maximum length of 7, using pop() to maintain it.
