Python Data Structures


title: The Python Data Structures

A data structure is a particular way of organizing data in a computer so that it can be used efficiently. Python comes with a robust set of inbuilt data structures. Some of the most commonly used ones are:

  • Lists — A sequence type where comma-separated values are ordered between square brackets and changeable.
  • Tuples — A sequence type where values are ordered between parentheses and unchangeable.
  • Dictionaries — An unordered collection that is changeable and indexed where values are held within curly braces in key: value pairs.
  • Sets
  • Strings

Majorly, the data structures can be divided into two categories:

  • Mutable — A mutable data structure is a structure whose state can be modified after it is created. Python Lists and Dictionaries are mutable.
  • Immutable — An immutable data structure can’t be modified. Example: Once a tuple is created, we can’t update the values inside it.
