use-namedtuple-record

When to Use

• Need tuple-like efficiency with named access
• Data should be immutable
• Will use as dict keys or in sets
• Want self-documenting code
• Replacing anonymous tuples with meaning
• Coordinates, points, records

When NOT to Use

• Need mutable fields (use dataclass)
• Need methods beyond basic access
• Complex initialization logic needed

The Pattern

Use namedtuple for lightweight, immutable records with named fields.
