Why is tuple faster than list

Python has two sorts of objects, mutable, and immutable Lists are changeable objects in Python, while tuples are immutable objects.

  • Tuples are kept in single cache memory. Tuples are immutable, therefore storing new items does not need more space.
  • Lists are divided into two blocks: one with most of the Python object metadata and one with a configurable range for the data.
  • It is the reason why a tuple is faster to create than a List.
  • It also explains why indexing time in tuples is quicker than in lists since indexing in tuples requires fewer references.
  • A tuple is made up of immutable items. (Objects that cannot be altered after they are created)
  • A list is made up of mutable items. (Objects that can be altered after they are created)
  • A Tuple has limited memory.
  • The List has a significant amount of memory.
  • A tuple is stored in a separate memory block.
  • The list is kept in two memory blocks. (One would be definite in size, while the other is variable in size, yet both are used to store data).
  • Constructing a tuple takes less time than creating a list.
  • Making a list takes longer because two memory blocks must be accessed.
  • A tuple element cannot be deleted or replaced.
  • A list element can be deleted or replaced.
