range in Index Based Operations

range() is frequently used to access list elements using their index positions.

This is useful when both the index and the value are required.

The range(len(items)) expression generates valid index values for the list.

This ensures controlled and predictable access to elements.

Index errors occur when an index goes outside the valid range of a list.

Using range(len(list)) helps prevent this issue.

The loop never exceeds the highest valid index.
