Python is the most popular programming language for beginners. It's used in web development, data analysis, artificial intelligence, automation, and many other fields. Best of all, it's completely free and installing it on your computer takes less than 10 minutes.
This guide shows you step by step how to install Python on Windows, Linux, and macOS — without assuming you already know anything about programming.
Before you start: Do you already have Python installed?
Open your terminal or command prompt and type:
python --version
Or on some systems:
python3 --version
If you see something like Python 3.12.0, you're all set. If it says the command doesn't exist, follow this guide.
How to install Python on Windows
Step 1: Download the installer
Go to python.org/downloads and click the yellow button that says "Download Python". The site will automatically detect that you're using Windows.
Step 2: Run the installer
Open the downloaded file. Important: before clicking "Install Now", check the box that says "Add Python to PATH". Without this, your computer won't recognize the python command from anywhere.
Step 3: Verify the installation
Open Command Prompt (CMD) and type:
python --version
You should see the version you just installed.
Step 4: Test that it works
Type:
python
You'll see a prompt with >>>. Type:
print("Hello, world")
Press Enter. If you see Hello, world, everything works. To exit, type exit() and press Enter.
How to install Python on macOS
Step 1: Check if it's already installed
macOS usually comes with Python 2.7 preinstalled, but that version is very old. Open Terminal and type:
python3 --version
If you see a 3.x version, you're ready. If not, continue.
Step 2: Install with Homebrew (recommended)
If you don't have Homebrew, install it by typing this in Terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Then install Python:
brew install python
Step 3: Verify
Type:
python3 --version
On macOS, always use python3 instead of python.
How to install Python on Linux
Most Linux distributions come with Python preinstalled. To verify:
python3 --version
If you don't have it or want to update:
Ubuntu/Debian:
sudo apt update
sudo apt install python3 python3-pip
Fedora:
sudo dnf install python3 python3-pip
Arch Linux:
sudo pacman -S python python-pip
What is pip and why does it matter?
pip is Python's package manager. It lets you install libraries created by other people with a single command. For example:
pip install requests
On Linux and macOS, use pip3 instead of pip.
First steps after installing Python
Now that you have Python, here are three ways to start practicing:
- Write scripts in a text file with the
.pyextension and run them withpython file.py. - Use the interactive console by typing
pythonorpython3in the terminal. - Install a code editor like Visual Studio Code (free) to get syntax highlighting, autocompletion, and error detection.
If You Want to Learn Python With a Clear Path
Installing Python is only the first step. What matters comes next: practicing with exercises, understanding errors, writing small programs, and learning how to explain what you built.
At Crezendo, we support people and teams who want to learn programming from zero through a practical path. If you already installed Python and want to turn it into a real skill, contact us so we can evaluate your starting point and build a learning plan.
