Challenge 2: Array Manipulation

NumPy offers a comprehensive set of tools for modifying and reshaping arrays. The key benefits include:

  • Diverse Capabilities: From reshaping to splitting, NumPy offers a wide range of functions to modify arrays as per requirements.
  • In-place Operations: Many NumPy functions can perform modifications in-place, meaning without creating a copy of the array, ensuring efficient memory usage.
  • Intuitive Syntax: Array manipulations often have a very readable and straightforward syntax, making the code self-explanatory.

The ability to seamlessly manipulate arrays is a cornerstone of many numerical and data science tasks, making these functions indispensable.

Tehtävä

Swipe to start coding

Manipulate arrays to change their shape and get desired elements.

  1. Extract the diagonal elements.
  2. Retrieve the elements in the second row.
  3. Extract the 2nd and 3rd rows and change their shape to (5, 2).

Ratkaisu
