- PIP package manager: PIP is a package manager for Python. It’s used to install and manage software packages written in Python. If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will have pip already, else we will guide you on how to get it.
That’s all you need to get started with Jupyter Notebook! It’s also recommended to have a reliable internet connection for a smooth and error-free installation.
In the next sections, we’ll guide you through each step of the installation process, starting with how to install Python. Let’s move forward!
How to Install Python
Python, an essential prerequisite for Jupyter Notebook, is a popular programming language known for its simplicity and readability. Installing Python on your machine is a fairly straightforward process. Here, we’ll guide you on installing Python on three major operating systems: Windows, macOS, and Linux.
Python Installation on Windows
- Visit the official Python website’s download page at https://www.python.org/downloads/windows/.
- Click on the link that says “Latest Python 3 Release – Python x.x.x” (where x.x.x denotes the latest version).
- Scroll to the files section and click “Windows x86-64 executable installer” for 64-bit or “Windows x86 executable installer” for 32-bit systems.
- After downloading the installer, run it. In the first installation screen, check the box at the bottom that says “Add Python x.x to PATH”. This will set your system’s PATH for Python.
- Click “Install Now”.
- Wait for the installation to complete, and then click “Close”.
Python Installation on MacOS
- Visit the official Python website’s download page at https://www.python.org/downloads/mac-osx/.
- Click on the link “Latest Python 3 Release – Python x.x.x”.
- Scroll down to the files section and click “macOS 64-bit Intel installer” or “macOS 64-bit universal2 installer” depending on your system.
- After downloading the installer, open it and follow the prompts to install Python.
- You can verify the installation by opening Terminal and typing
python3 --version. You should see Python’s version number.
Python Installation on Linux
Python is usually preinstalled on most Linux distributions. However, you might want to upgrade to the latest version. Here’s how you can do it:
For Ubuntu, you can use the following commands:
sudo apt update sudo apt install python3
For CentOS, you can use the following commands:
sudo yum update sudo yum install python3
Please check the specific documentation for Python installation instructions for other Linux distributions.
You can verify the installation by opening a terminal and typing
python3 --version. You should see Python’s version number.
Once you install Python, you are one step closer to getting Jupyter Notebook running on your machine. The next section cover setting up a Python virtual environment, an optional but highly recommended step for managing Python packages.
Setting up a Python Virtual Environment
Python’s Virtual Environment is a self-contained directory tree that includes a Python installation for a particular version of Python, plus several additional packages. It’s a best practice to isolate your Python project’s specific library dependencies in virtual environments, providing a more reliable and controlled development environment.
Let’s walk through the process of setting up a Python virtual environment. This process is the same across all major operating systems.
- Install the
virtualenvpackage: Open your command prompt or terminal, and run the following command to install the
virtualenvpackage. This tool lets us create isolated Python environments:
pip install virtualenv
- Create a new virtual environment: Navigate to the directory where you want to create your new virtual environment. Once you’re in that directory, run the following command:
myenv with the name, you want to give to your virtual environment. This command creates a new directory containing the virtual environment files with the same name.
- Activate the virtual environment: Before we can use the virtual environment, we need to activate it. The command for this varies a bit depending on your operating system:
- On Windows, run:
- On macOS/Linux, run:
source myenv/bin/activateIn both commands, replace
myenvwith the name you gave to your virtual environment.
After you’ve activated your virtual environment, your command prompt will show the name of your virtual environment, something like this:
(myenv) C:\path\to\your\directory>. This indicates that the virtual environment is active.
Any Python package installed in the virtual environment is isolated from the global Python environment.
In the next section, we’ll guide you on installing Jupyter Notebook in this isolated environment, ensuring a clean and conflict-free setup. Let’s move on!
Installing Jupyter Notebook using PIP
With your virtual environment set up, you can install Jupyter Notebook. The process is straightforward, thanks to Python’s package manager, PIP.
Ensure your virtual environment is active (you should see the name of your environment in your terminal or command prompt). If it’s inactive, refer to the previous section to activate it.
Once your virtual environment is active, follow these steps:
- Install Jupyter Notebook: Run the following command in your terminal:
pip install notebook
This command tells PIP to install the ‘notebook’ package containing the classic Jupyter Notebook application.
- Verify the Installation: After the installation completes, you can verify it by running:
jupyter notebook --version
This command would print the installed version of Jupyter Notebook if the installation were successful.
- Launch Jupyter Notebook: You can start the Jupyter Notebook interface in your browser by running:
This command will print information about the notebook server in your terminal, including the web application URL (by default, http://localhost:8888).
Upon launching, your default browser should automatically open to this URL. You can manually open this URL in your browser if it doesn’t.

Running Your First Jupyter Notebook
Congratulations on successfully installing Jupyter Notebook! Now, let’s walk through creating and running your first notebook.
- Launch Jupyter Notebook: If you’ve closed it, relaunch Jupyter Notebook by running
jupyter notebookit in your terminal or command prompt. This command will open the Jupyter Notebook interface in your default web browser.
- Create a new Notebook: In the Jupyter Notebook interface, navigate to the right-hand side of the screen and click on the ‘New’ button. Then, select ‘Python 3’ from the dropdown list. A new tab will open with your fresh notebook.
- Understanding the Interface: Each Jupyter Notebook is composed of cells. A cell is a multiline text input field, and its contents can be executed by using Shift-Enter, or by clicking either the “Play” button in the toolbar or Cell > Run in the menu bar. The cell’s type determines the execution behavior of a cell. There are three types of cells: code cells, markdown cells, and raw cells. In most cases, you’ll be working with code and markdown cells.
- Running Python Code: Click on the first cell and try typing some Python code, such as:
Hit ‘Shift + Enter’ to run the cell. The output of the cell will appear below the code.
- Writing Markdown Text: You can use Markdown cells to explain your code and findings. Markdown is a lightweight markup language for creating formatted text. To create a Markdown cell, click on a cell, go to the ‘Cell’ menu, select ‘Cell Type’, and then ‘Markdown’. Now, you can write text in this cell. Try typing some text and then run the cell as you did before.
- Saving Your Notebook: To save your work, go to ‘File’ and then ‘Save and Checkpoint’, or just hit ‘Ctrl + S’.
You’ve created and run your first Jupyter Notebook. In the following sections, we’ll explore how to troubleshoot the Jupyter Notebook’s common installation issues effectively. Let’s proceed!
Troubleshooting Common Installation Issues
Like any software installation, you may encounter some challenges when installing Python or Jupyter Notebooks. Here are some common issues you might face and solutions to get you past them.
- Python not recognized as a command: If you see a ‘Python is not recognized as an internal or external command’ error after installing Python, this likely means that Python was not added to your system’s PATH. To fix this, you can manually add Python to your PATH variable. The method varies between operating systems and versions, so a quick internet search with your specific OS will provide the most accurate steps.
- PIP not working: If you’re having trouble using pip, it might be that pip isn’t installed, or it’s an issue with your PATH variable. Python 3 comes with pip preinstalled, so make sure you’re using Python 3. If you still have issues, try reinstalling Python and ensure the ‘pip’ box is checked during installation.
- Issues installing Jupyter Notebook: If you’re encountering errors while installing Jupyter Notebook, it might be due to an older version of PIP or Python. Make sure both are up-to-date. You can update pip by running
pip install --upgrade pipand update Python by downloading the latest version from the Python website.
- Jupyter command not found: If you have installed Jupyter Notebook, but your system can’t seem to find it (i.e., you see a ‘jupyter: command not found’ error), this is likely because the location where pip installed Jupyter is not on your system’s PATH. As mentioned above, you can resolve this by adding the installation location to your PATH.
- Issues running Jupyter Notebook: If Jupyter Notebook doesn’t launch automatically, manually launch it by entering the URL in the terminal (usually http://localhost:8888) into your browser’s address bar. If the interface is still not showing up, ensure no firewall or security software is blocking Jupyter Notebook.
Remember, it’s okay to encounter problems during the installation process. It’s part of the learning experience. Don’t hesitate to search online for the errors you’re seeing – it’s likely that others have encountered the same issues and found solutions. Happy troubleshooting!
Best Practices for Using Jupyter Notebook with Python
Utilizing Jupyter Notebook effectively can make your Python programming more efficient and enjoyable. Here are some best practices to ensure you’re getting the most out of your Jupyter Notebook experience:
- Organize Your Code with Cells: Jupyter Notebook’s cell structure is its biggest strength. Make good use of it by organizing your code into logical sections. Each cell should accomplish a specific task or represent a specific step in your analysis or modeling process.
- Comment Your Code: Like any other programming environment, commenting on your Python code in Jupyter Notebooks is a good habit. Even though you can write rich text in markdown cells, inline comments in your code cells can provide context directly tied to the code.
# Calculate the sum of the list sum_list = sum(my_list)
- Use Markdown Cells for Documentation: Markdown cells are perfect for documenting your analysis process, explaining your reasoning, noting observations, and providing another context. This is what makes Jupyter Notebook great for data storytelling.
- Show Your Work: Jupyter Notebook allows you to display your Python data structures in a readable format. This feature shows intermediary steps in your data analysis or modeling process. This can be especially useful for debugging and explaining your process to others.
# Display the content of the list print(my_list)
- Keep Your Notebooks Reproducible: Try to keep your notebooks self-contained and reproducible. If someone else were to run your notebook, they should get the same results. This might involve setting seeds for random number generators, making sure any data files you use are accessible, and providing explicit instructions for any manual steps.
- Regularly Save Your Work: Jupyter automatically saves your notebook every few minutes, but you should also get into the habit of manually saving your work. You can do this by clicking ‘File’ > ‘Save and Checkpoint’, or by simply pressing ‘Ctrl + S’.
- Clear Your Output: When sharing your notebook, it can be helpful to clear your output data first. This makes the notebook smaller and encourages others to run the code themselves. You can clear output via ‘Cell’ > ‘All Output’ > ‘Clear’.
- Use Jupyter Extensions: Jupyter has many extensions that add useful functionality. These can be installed with pip and activated in Jupyter. For instance, the
nbextensions_configuratorextension provides a convenient way to configure and manage your Jupyter extensions.
Applying these best practices makes your Jupyter Notebook usage more efficient and productive. Happy coding!
