Production-Ready Code Generation

Write [language] code to solve this problem:

Problem: [describe what the code needs to do] Input: [what data/parameters it receives] Expected output: [what it should return/produce] Constraints: [performance needs, libraries to use/avoid, style preferences]

Requirements:

• Handle these edge cases: [list specific cases like empty input, nulls, errors]
• Code should be readable (clear variable names, logical structure)
• Include brief comments explaining non-obvious decisions
• Follow [specific style guide if applicable]

Example scenario: [provide one concrete use case]

Success criteria: I can drop this into my project with minimal modification.
