Python is an incredibly powerful programming language with a vast ecosystem of libraries and tools known as “packages.” These packages can help you perform complex tasks with just a few lines of code, saving you time and effort while improving the quality of your work.

However, before you can use these packages, you need to import them into your script or project. This guide will take you through everything you need to know about importing packages in Python, from basic imports to more advanced techniques.

Basic Imports

To start using a package in your Python script, you first need to add an import statement at the top of your file. For example, if you want to use the popular NumPy library for numerical computations, you would include the following line:

import numpy

Once imported, you can now access all functions, classes, and variables defined within the package via its namespace — in this case, numpy. To call a function such as array(), you'd do so like this:

import numpy
my_array = numpy.array([1,2,3])
