Mis on NumPy teek ja milleks seda Pythonis kasutatakse?

NumPy is a library for the Python language that provides support for large multidimensional arrays and matrices, as well as a large number of high-level mathematical functions to work with them. It is used for efficient numerical computations, scientific analysis, and data processing.

Main advantages of NumPy:

• Fast operations on arrays thanks to its implementation in C.
• Convenient functions for linear algebra, statistics, Fourier transforms, and more.
• Foundation for many other libraries in data analysis and machine learning.

Example of usage:

import numpy as np

# Creating an array from a list
arr = np.array([1, 2, 3, 4])

# Multiplying by a number
arr2 = arr * 2
print(arr2)  # [2 4 6 8]
