Python is a language that allows you to create dynamic programs. Programming languages rely on data structures and algorithms, which are important and difficult to master. This is why hiring managers choose Python data structure interview questions when interviewing candidates for software engineering positions.

Going through essential theoretical concepts and exercising problem-solving skills is the best method to prepare for data structures in Python interview questions. It is highly advised that you answer at least 1-2 Python data structures interview questions per day if you have a technical interview coming up.

  • Data structure is a fundamental concept of any programming language, essential for algorithmic design.
  • It is used for the efficient organization and modification of data.
  • DS is how data and the relationship amongst different data is represented, that aids in how efficiently various functions or operations or algorithms can be applied.
  • There are two types of data structures:
    • Linear data structure: If the elements of a data structure result in a sequence or a linear list then it is called a linear data structure. Example: Arrays, Linked List, Stacks, Queues etc.
    • Non-linear data structure: If the elements of data structure results in a way that traversal of nodes is not done in a sequential manner, then it is a non linear data structure. Example: Trees, Graphs etc.
  • Data structures form the core foundation of software programming as any efficient algorithm to a given problem is dependent on how effectively a data is structured.

  • Identifiers look ups in compiler implementations are built using hash tables.
  • The B-trees data structures are suitable for the databases implementation.
  • Some of the most important areas where data structures are used are as follows:
  • Artificial intelligence
  • Compiler design
  • Machine learning
  • Database design and management
  • Blockchain
  • Numerical and Statistical analysis
  • Operating system development
  • & Speech Processing
  • Cryptography
  • Q Enumerate differences between a list and a tuple in Python

    This is one of the basic Python data structures interview questions. Here’s how you can answer it:

    The key differences between a list and a tuple are:
