Arrays

Arrays are linear, homogenous, and static data structures.
Arrays store data in an order.
All data in an array must be of the same data type.
Each element of an array has a corresponding index value, starting with index 0.
The array module is used to work with arrays in Python.
You can iterate over arrays using a for loop.
A two-dimensional array consists of rows and columns.
You can iterate over a two-dimensional array using nested for loops.
The len() function returns the length of an array.
It is not possible to modify the size of an array once it is created.

Tuples

Tuples are similar to arrays but are immutable, meaning their elements cannot be modified after creation.
Tuples can contain elements of different data types.
You can access elements of a tuple using indexing, starting with index 0.
Tuples are useful for representing a fixed set of data.

Records

Records are similar to arrays, but can store elements of different data types (non-homogeneous).
Records are used to represent a single entity, with fields containing information about that entity.
The fields in a record are not accessed by index, instead they are accessed by their unique name.

This quiz covers the fundamental concepts of arrays, tuples, and records in Python. Learn about their characteristics, differences, and how to manipulate them. Test your knowledge with questions on indexing, immutability, and data types.
