range vs list

A list stores all elements explicitly in memory.

A range object stores only start stop and step values.

The range object consumes significantly less memory.

Iteration speed is similar for both in most cases.

However creating a list has an additional memory allocation cost.

Range objects are faster to create and more memory efficient.

Use range() when You only need to iterate Memory efficiency matters Sequence size is large

Use list when You need random access modification You require list methods Data must be stored explicitly

Choosing the correct structure improves performance and code quality.
