Analyze Python Functions: Improve Readability and Efficiency
Scenario
During a Zoom interview, you will be presented with three short Python functions that are part of an existing data-science pipeline.
Task
Your task is to conduct a line-by-line code review of these functions. For each line, explain its purpose and why it is present.
Deliverables
Identify and propose at least three significant improvements across the functions. These improvements can cover various aspects, including:
- Readability
- Efficiency
- Edge-case handling
- Testing strategies
- Overall code structure
Hints for Improvement
Consider aspects such as:
- Naming conventions for variables and functions
- Opportunities for vectorization
- Inclusion of docstrings
- Robust exception handling mechanisms
- Principles of separating concerns within the code
