Which Python Is Best For AI?

Python is widely recognized as one of the go-to programming languages for AI development. With its versatile and extensive libraries, Python offers a range of options for implementing artificial intelligence algorithms. However, when it comes to selecting the best Python version for AI, you may find yourself pondering over the choices. In this article, we take a closer look at the different versions of Python and examine which one reigns supreme for AI applications.

Python Versions for AI

When it comes to AI development, choosing the right programming language is crucial. Python, with its simplicity and versatility, has become one of the most widely used languages in AI. However, there are two versions of Python currently in use: Python 2 and Python 3. In this article, we will explore the differences between these versions and analyze their suitability for AI development.

Python 2


Python 2 was released in 2000 and quickly gained popularity among AI developers. Its simplicity and extensive library support made it an attractive choice for AI projects. However, Python 2 is now considered a legacy language, as its development and major support officially ended in 2020. Despite this, some AI projects still utilize Python 2 due to compatibility issues with older libraries.


One of the key advantages of Python 2 is its vast library support. Many popular AI libraries were initially developed for Python 2, giving developers access to a wide range of tools and resources. Additionally, Python 2 is known for its stability, as it has been extensively tested over the years. This stability makes it a reliable choice for AI projects that require consistency.


While Python 2 has its merits, it also has some drawbacks that should be considered. The most significant drawback is its lack of support for certain modern language features and improvements. Python 2 does not have the same level of performance optimization as Python 3, which can impact the efficiency of AI algorithms. Moreover, Python 2 has a different syntax than Python 3, which may require additional effort to transition from one version to another.

Python 3


Python 3 was released in 2008 and was designed to address the limitations of Python 2. It introduced several significant changes, including improvements in syntax, performance, and library support. Python 3 is the current and recommended version for AI development, offering a more modern and efficient programming environment.


Python 3 brings several benefits to the table, making it a popular choice for AI projects. One of the notable advantages is its improved syntax, which enhances readability and reduces the chance of errors. Furthermore, Python 3 offers better support for Unicode, making it easier to work with non-English languages and text data. Additionally, Python 3 has improved memory management, resulting in enhanced performance and efficiency.


Despite its advantages, Python 3 is not without its drawbacks. One of the main challenges developers face when transitioning from Python 2 to Python 3 is the compatibility issue with older libraries. While many libraries have been updated to support Python 3, there are still cases where transitioning can be time-consuming and challenging. Moreover, some developers who are already familiar with Python 2 may find it difficult to adapt to the changes in syntax and programming conventions introduced in Python 3.

Popular Python Libraries for AI

In addition to choosing the right version of Python, utilizing the appropriate libraries is essential for successful AI development. Here are some of the most popular Python libraries used in the field of AI.


TensorFlow is a widely used open-source library developed by Google. It provides a comprehensive platform for building and deploying machine learning models. TensorFlow offers a wide range of tools, from high-level APIs for quick development to low-level operations for maximum customization. With its immense popularity and vast community support, TensorFlow has become the go-to library for many AI developers.


PyTorch is another popular library that has gained significant traction in recent years. Developed by Facebook’s research lab, PyTorch focuses on providing a flexible and dynamic approach to deep learning. Its computational graph system enables developers to build complex neural networks with ease. PyTorch’s intuitive interface and extensive documentation make it an excellent choice for researchers and developers alike.


Scikit-learn is a powerful machine learning library that provides a user-friendly interface for various AI tasks. It offers a wide range of algorithms and tools for data preprocessing, classification, regression, clustering, and more. Scikit-learn’s simplicity and ease of use have made it a popular choice among beginners and experienced developers alike.


Keras is a high-level neural networks API that runs on top of TensorFlow or Theano. It provides a simple yet powerful interface for building and training deep learning models. Keras abstracts away the complexity of low-level operations, allowing developers to focus on the model architecture and experimentation. Its user-friendly design and extensive community support make it a top choice for AI beginners and researchers.


Natural Language Toolkit (NLTK) is a library specifically designed for working with human language data. It provides tools for text processing, tokenization, stemming, tagging, and parsing. NLTK also includes a wide range of datasets and resources for language analysis and machine learning. With NLTK, developers can easily preprocess and analyze textual data, making it indispensable for AI projects involving natural language processing.


Choosing the right version of Python for AI development is crucial to ensure a smooth and efficient workflow. Python 3 is generally recommended due to its improved syntax and performance optimization. However, for projects that heavily rely on older libraries, Python 2 may still be a viable option. It is important to consider the pros and cons of each version and assess the compatibility requirements of the project.

In addition to Python versions, utilizing the right libraries is essential for AI development. TensorFlow, PyTorch, Scikit-learn, Keras, and NLTK are some of the most popular libraries in the field. Each library has its own strengths and can be beneficial depending on the specific AI tasks at hand.

In conclusion, Python 3, with its modern features and improved performance, is the recommended version for AI development. However, it is crucial to carefully evaluate the compatibility requirements and choose the appropriate libraries to maximize the potential of your AI projects. With the right combination of Python version and libraries, you can embark on a successful AI journey.
