📄 6% (0.06x) speedup for Command.invoke in src/click/core.py

⏱️ Runtime : 34.5 microseconds 32.7 microseconds (best of 27 runs)

📝 Explanation and details

To optimize the provided code, I will streamline some logic, avoid redundant checks, and combine dictionary operations. Here's the optimized version of the script.

Here's a summary of optimizations.

  1. Simplified context_settings Initialization: Initialized self.context_settings directly using a default dictionary if None is provided.
  2. Optimized String Concatenation: Combined the handling of deprecation messages into a single statement to avoid repeated string concatenation.
  3. Removed Redundant Checks.
    • Directly checked self.callback without is not None because non-None values are considered True in Python.
    • Removed redundant docstring comments for methods where context is self-explanatory.

These changes should yield marginal performance improvements primarily due to reduced condition-checking overhead and more efficient string handling.

To optimize the provided code, I will streamline some logic, avoid redundant checks, and combine dictionary operations. Here's the optimized version of the script.



Here's a summary of optimizations.

1. **Simplified `context_settings` Initialization**: Initialized `self.context_settings` directly using a default dictionary if `None` is provided.
2. **Optimized String Concatenation**: Combined the handling of deprecation messages into a single statement to avoid repeated string concatenation.
3. **Removed Redundant Checks**.
    - Directly checked `self.callback` without `is not None` because non-None values are considered `True` in Python.
    - Removed redundant docstring comments for methods where context is self-explanatory.

These changes should yield marginal performance improvements primarily due to reduced condition-checking overhead and more efficient string handling.
