How to Install Python on Windows, Mac, and Linux

In this post, we will learn how to intall Python on Windows, Mac, and Linux.

Install Python on MacOS via Official Installer

Download Python Installer here: https://www.python.org/downloads/

Then, run the installation process.

To verify that Python is installed correctly, open a terminal window and type the following command:

python3 --version

Set Python3 as the Default

To set Python 3 as the default version, you can create an alias in your .bashrc or .bash_profile file.

alias python=python3

For zshrc, you can add the alias to your .zshrc file.

echo 'alias python="python3"' >> ~/.zshrc
source ~/.zshrc

Install Virtual Environment

venv is a built-in module in Python that allows you to create virtual environments for your Python projects.

Virtual environments are isolated environments that contain their own Python interpreter and packages, which helps you manage dependencies and avoid conflicts between different projects.

# Create a virtual environment (this creates folder named myenv)
python3 -m venv myenv

# Activate virtual environment
source myenv/bin/activate

# Deactivate virtual environment
deactivate

# Remove virtual environment
rm -rf myenv
