Getting Started with Numpy
You should know the fundamentals of Python programming before getting into Numpy learning. Before beginning with Numpy, you are advised to take an introductory Python course or read some appropriate tutorials for beginners. After you have a firm understanding of Python basics, you can begin using Numpy by doing the following:
Install Numpy
The best way to learn Numpy is by installing it on your computer. You can do this by using the pip package manager in Python:
“`
pip install numpy
“`
Import Numpy
Next, you need to import the Numpy library into your Python code. This will allow you to access all of its functions and features:
“`Python
import numpy as np
“`
Create Numpy Arrays
The core data structure in Numpy is the ndarray, a multidimensional array object with powerful capabilities. You can create an ndarray using the `np.array()` function:
“`Python
arr = np.array([1, 2, 3, 4])
“`
You can also create multidimensional arrays by passing in a nested list:
“`Python
arr = np.array([[1, 2, 3], [4, 5, 6]])
“`
