Introduction
🧑💻 New to Linux or LabEx? We recommend starting with the Quick Start with Linux course.
Hi there, welcome to LabEx! In this first lab, you'll learn the classic "Hello, World!" program in NumPy.
Click the Continue button below to start the lab.
Hello NumPy
Let's start by importing the NumPy library. Open a new terminal and type:
python3

This will open a Python interpreter. Now, let's import NumPy:
import numpy as np
NumPy is now imported and ready to use. Let's create a NumPy array. We'll start with a simple list of numbers:
a = np.array([10, 20, 30, 40])
We can print the array by typing:
print(a)
