In the realm of Python programming, package managers play a crucial role. These indispensable tools allow us to install, manage, and update the libraries that empower our applications. Pip, short for “Pip Installs Packages,” is a fundamental package manager for Python. However, the emergence of Python 3, a major revision of the language, introduced a seemingly redundant counterpart: pip3. This article delves into the intricacies of these two tools, revealing their differences and guiding you toward a seamless understanding of their roles.
The Birth of Pip and the Arrival of Pip3
Pip’s Genesis
Pip, the original Python package manager, first saw the light of day in 2008. Its creation was driven by the need for a standardized, user-friendly way to install and manage Python packages. Prior to pip’s arrival, the process of installing and maintaining packages was often arduous and inconsistent. Pip offered a much-needed solution, streamlining the process and making it accessible to all Python developers.
The Rise of Python 3 and Pip3
Python 3, released in 2008, brought about a major shift in the language. To support compatibility between different versions, developers introduced a new version of the package manager: pip3. This distinct version of pip was specifically designed to work with Python 3, while the original “pip” was retained for compatibility with Python 2.

The Heart of the Matter: Understanding the Difference
The key difference between pip and pip3 lies in their underlying purpose and compatibility. Pip3, being tailored for Python 3, effectively isolates the process of installing and managing packages for Python 3 projects. In contrast, traditional pip, designed for older versions of Python, remains dedicated to its original purpose—managing packages within Python 2 environments.
When to Use Pip and When to Use Pip3
The choice between pip and pip3 hinges on the version of Python you are using and the specific project you are working on.
For Python 3 Projects: Utilize Pip3
If you are working on a project using Python 3, it is strongly recommended to use pip3. This dedicated version of pip ensures that you are installing packages specifically for Python 3, avoiding any potential compatibility issues that might arise from mixing package versions between Python 2 and Python 3.
For Python 2 Projects: Stick with Pip
Similarly, if your project still relies on Python 2, pip remains the ideal choice for managing its packages. Using pip3 with Python 2 will more than likely lead to errors and frustrations.
Navigating the Modern Python Ecosystem
In the increasingly dominant Python 3 world, the need for “pip3” appears less compelling. While a majority of developers have transitioned to Python 3, many still encounter the “pip3” label, sparking confusion. Fortunately, the landscape is evolving to simplify the process. Modern systems and package managers have adapted, often using “pip” for both Python 2 and Python 3, making the distinction less relevant.
A Simplified Future: The Convergence of Pip and Pip3
To address the potential confusion, developers and system administrators are actively working toward a streamlined experience. The latest versions of pip are often configured to work seamlessly with both Python 2 and Python 3. As the adoption of Python 3 continues and Python 2 gradually fades into history, the distinction between “pip” and “pip3” is expected to become less prominent, ultimately converging into a single, unified package manager for all versions of Python.
Unveiling the Magic: A Real-World Example
Let’s consider a practical scenario to illustrate the difference between pip and pip3.
Suppose you are building a web application using the Flask framework, a popular Python web framework. For this project, you intend to use Python 3. To work smoothly, you need to install several third-party libraries, such as Flask itself, Jinja2 (for templating), and SQLAlchemy (for database interactions).
Using pip3, you would navigate to your project’s directory and execute the following commands:
pip3 install Flask
pip3 install Jinja2
pip3 install SQLAlchemyThese commands would successfully install the desired packages for your Python 3 project.
However, if you attempted to install these packages using traditional pip in the same directory, the installation process might encounter errors. This is because pip would try to install these packages for your default Python version, which might be Python 2, leading to incompatibility issues.
In this instance, pip3 acts as a dedicated package manager for Python 3, ensuring that you are installing the correct versions of libraries for your specific project.
Difference Between Pip And Pip3
Conclusion: Embracing the Simplicity
The differences between pip and pip3, while significant in the past, are gradually becoming less relevant as the Python community embraces Python 3 as its primary language. Understanding this historical context and the ongoing evolution provides valuable insights into the world of Python package management. As the Python ecosystem evolves, the focus will shift towards a unified and seamless experience with pip, simplifying the process of installing and managing packages for diverse projects.
So, the next time you encounter “pip” and “pip3,” remember that they represent a historical evolution towards a streamlined approach to Python package management. By understanding the nuances and the direction of the Python community, you are empowered to navigate the ever-changing waters of Python’s package management landscape with confidence and ease.
