⚡️Codeflash found 17% (0.17x) speedup for confirm in codeflash/cli_cmds/themed_prompts.py
⏱️ Runtime : 412 microseconds → 350 microseconds (best of 14 runs)
📝 Explanation and details
The optimization eliminates intermediate variable assignments by directly chaining object creation and method calls in a single return statement.
Key Changes:
- Removed the
widgetvariable assignment that stored theInquirerConfirminstance - Removed the
appvariable assignment that stored theCodeflashThemedAppinstance - Combined both instantiations and the
.run()call into one expression
Why This Improves Performance:
In Python, variable assignments create name bindings in the local namespace, which involves dictionary operations and reference counting. By eliminating these intermediate variables, the optimization reduces:
- Local namespace lookups and assignments
- Temporary object reference management
- Memory allocation for storing variable references
The line profiler shows the optimization maintains the same computational cost for the expensive InquirerConfirm creation (98%+ of total time), while reducing overhead from variable management operations.
Impact on Workloads:
This optimization provides the most benefit when the confirm function is called frequently, as the 17% speedup compounds across multiple calls. The test results show consistent improvements ranging from 1-20% across different scenarios, with the best gains on simpler operations where variable overhead represents a larger percentage of total execution time.
Test Case Performance:
The optimization performs well across all test scenarios, with particular benefits for edge cases involving special characters and type validation where the function execution is lighter and variable overhead becomes more significant relative to total runtime.
