Industries, such as finance, healthcare, government, aerospace, entertainment, and more, are adapting Python for various tasks, including data analysis, automation, web development, machine learning, and artificial intelligence applications.

C. Overview of Python installation and use on different operating systems, focus on macOS

Python can be installed and run on various operating systems, including Windows, macOS, and Linux. This article will focus on installing and using Python on a MacBook, which uses the macOS operating system.

Installing Python on a MacBook

A. Checking if Python is pre-installed on macOS

macOS comes pre-installed with Python, usually Python 2.7. To check the Python version installed on your MacBook, open the Terminal app and type the following command:

python –version

If Python 3 is installed, you can check its version using:

python3 –version

B. Choosing a Python version to install

It’s important to select the most appropriate Python version for your specific needs. Python 2.x is legacy, while Python 3.x is the present and future of the language. Most modern applications and libraries are developed for Python 3. It’s recommended to install the latest stable release of Python 3 unless you have a specific reason to use Python 2.

C. Installing Python using package managers

1. Homebrew

Homebrew is a popular open-source package manager for macOS that allows you to install various software packages easily. To use Homebrew, first, install it on your MacBook. You can find the installation instructions on the Homebrew official website.

Once installed, you can install the latest Python version by running the following command in the Terminal:

brew install python

2. MacPorts

MacPorts is another package manager for macOS, similar to Homebrew. To use MacPorts, first, install it on your MacBook. You can find the installation instructions on the MacPorts official website.

Once installed, install Python using the following command in the Terminal:

sudo port install python38

Replace “python38” with the desired Python version.

3. Anaconda

Anaconda is a popular Python and R distribution, mainly used for data science, machine learning, and scientific computing tasks. It comes with various data science packages and libraries pre-installed, making it convenient for users working in these domains.

First, download the Anaconda installer suitable for your macOS from the official Anaconda website. Once downloaded, follow the installation instructions provided on the website.

D. Installing Python manually from the official website

You can also install Python manually using the official Python installer from the Python website. Download the macOS installer for the desired Python version, then run the installer and follow the prompts to install Python on your MacBook.

E. Verifying Python installation and version

After installing Python using any of the methods mentioned above, verify the installation by checking the Python version:

python3 –version

This command should display the installed Python version.

Setting up a Python development environment on a MacBook

A. Integrated Development Environment (IDE) options

Setting up a suitable IDE is essential for a smooth and efficient Python development experience. Some popular IDE options for Python development on macOS are:

1. PyCharm

PyCharm is a popular and powerful IDE developed specifically for Python development by JetBrains. It comes in two editions: Community (free) and Professional (paid). The Community Edition provides essential features such as syntax highlighting, code completion, and debugging, while the Professional Edition adds advanced features like remote development and additional frameworks support.

2. Visual Studio Code

Visual Studio Code (VSCode) is a lightweight, open-source, and general-purpose code editor developed by Microsoft. With the Python extension, it becomes a powerful Python development environment, providing features like syntax highlighting, code completion, debugging, and more.

3. Jupyter Notebook

Jupyter Notebook is an open-source web-based interactive development environment specially designed for data science, machine learning, and scientific computing tasks. It supports Python and other programming languages and lets you create and share documents containing live code, equations, visualizations, and narrative text.

4. Sublime Text

Sublime Text is a popular, lightweight, and fast cross-platform text editor with Python support. It provides essential features like syntax highlighting, code completion, and customization options. You can extend Sublime Text’s functionality with plugins and additional features.

B. Installing and setting up the chosen IDE

Once you have chosen an IDE, follow the installation instructions provided by the respective IDE’s official website. After installing, configure the IDE to use the installed Python interpreter.

C. Creating and configuring a virtual environment

Virtual environments allow you to manage separate projects with different dependencies without conflicts. To create and configure a virtual environment:

1. Using venv

Python 3.3+ comes with the built-in `venv` module for creating virtual environments. To create a new virtual environment, open the terminal, navigate to your project directory, and run:

python3 -m venv myvenv

Replace “myvenv” with your desired virtual environment name. To activate the virtual environment, run:

source myvenv/bin/activate

2. Using Conda (for Anaconda users)

If you installed Python using Anaconda, you can create a virtual environment using the `conda` command. Open the terminal and run:

conda create -n myenv python=3.8

Replace “myenv” with your desired virtual environment name and “3.8” with your desired Python version. To activate the virtual environment, run:

conda activate myenv

D. Installing Python packages and libraries using pip

Python packages and libraries can be installed using the package installer for Python (pip). You can install packages globally or within a virtual environment.

1. Installing globally

To install packages globally, open the terminal and run:

pip install package_name

Replace “package_name” with the desired package name.

2. Installing within a virtual environment

To install packages within a virtual environment, first, activate the virtual environment, then run the same pip command as above.

Running Python scripts and programs on a MacBook

A. Running Python commands in the terminal

1. Using python or python3 command

To run Python scripts using the terminal, simply type the following command:


Replace “” with your Python script’s filename.

2. Interactive Python shell (REPL)

To run Python commands interactively, open the terminal and type:


This will open the Python interactive shell (REPL) where you can execute Python commands one by one.

B. Running Python scripts using an IDE

Python scripts can also be executed within your chosen IDE. Follow the instructions provided by the IDE’s official documentation to learn how to run Python scripts using that particular IDE.

C. Understanding Python file organization

Python follows a hierarchical structure for organizing code in files and folders. A Python script typically contains a single .py file, whereas a Python package is a collection of .py files organized in a specific directory hierarchy.
