Arrays are a fundamental data structure in programming. In this tutorial, we will delve into the advanced concepts of arrays. By the end, you will have a deeper understanding of how to manipulate and utilize arrays effectively.

Understanding Advanced Array Concepts

1. Multi-dimensional Arrays

Multi-dimensional arrays are arrays within arrays. They are used to represent data in a tabular format, like rows and columns in a spreadsheet.

  • A 2D array is a matrix with rows and columns.
  • A 3D array is an array of arrays, and so on.
# Example of a 2D array in Python
array_2d = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

2. Array Slicing

Slicing allows you to extract a part of an array. It is useful for accessing specific elements or ranges.

# Example of slicing a 2D array
sliced_array = array_2d[1:3, 1:3]

3. Array Manipulation

Arrays can be manipulated in various ways, such as sorting, reversing, and concatenating.

# Example of sorting an array
sorted_array = sorted(array_2d, key=lambda x: x[0])
