Introduction
Python programming language is widely used due to its simplicity and versatility. But with the constant development of Python versions, users are left with confusion regarding which version to use. This article aims to provide a simple guide on the comparison of Python versions.
Understanding Python version numbering scheme
Python follows a specific numbering scheme where each version number comprises of three parts separated by dots: major.minor.micro. Major version updates indicate significant changes to the language, minor version updates include new features, and micro version updates comprise of bug fixes and small improvements.
Python 2 vs Python 3
Python 2 and Python 3 are the two major versions with significant differences. Python 2 was popular until 2020, but Python 3 has completely replaced it as Python 2 reached the end of its life cycle.
Differences between Python 2 and Python 3
| Python 2 | Python 3 |
|---|---|
| Includes print as a statement | Includes print as a function |
| Uses ASCII for string literals | Uses Unicode for string literals |
| Does not contain annotations | Has optional type annotations |
Why Python 3 is preferred over Python 2
Python 3 provides several advantages over Python 2, including improved syntax, better Unicode support, and better handling of data types. Moreover, Python 2 will no longer receive any security updates or bug fixes, making it an unsafe option to continue.
Python 3 Versions
Python 3 also has its own versioning scheme, with new releases frequently. Currently, the latest stable release is Python 3.9, which offers several improvements compared to previous versions.
Comparison of Python 3.8 and Python 3.9
| Python 3.8 | Python 3.9 |
|---|---|
| Introduced an f-string debugging feature | Introduced dictionary union operators |
| Added support for positional-only parameters | Added support for flexible function and variable annotations |
Which version of Python 3 to use?
It’s always recommended to use the latest stable release for security and performance reasons. However, certain libraries might not support the latest version, so it’s important to check compatibility before upgrading to a new version.
Conclusion
The Python language continues to evolve, and keeping up with the latest version can be challenging. This article provides some clarity on the differences between major Python versions and offers recommendations for which version to use. Ultimately, the choice of version depends on individual project requirements, but using the latest stable release is often the best practice.

People Also Ask about Python Version Number Comparison: A Simple Guide
Python is a high-level programming language that is widely used in various fields such as web development, data science, machine learning, and artificial intelligence. As Python evolves, new versions are released with new features and improvements. Here are some common questions people ask about Python version number comparison:
- What is the latest version of Python?
- What is the difference between Python 2 and Python 3?
- Can I run Python 2 and Python 3 on the same computer?
- How do I check my Python version?
- Do I need to upgrade to the latest Python version?
The latest stable version of Python is version 3.10.0, which was released on October 4th, 2021.
Python 2 and Python 3 are two major versions of Python that are not fully compatible with each other. Python 3 introduced several changes and improvements to the language, including better Unicode support, improved syntax, and better handling of exceptions.
Yes, it is possible to have both Python 2 and Python 3 installed on the same computer. However, it is recommended to use virtual environments or containers to manage multiple Python versions to avoid conflicts.
To check the installed version of Python on your computer, open a terminal or command prompt and type python –version. This will display the version number.
It depends on your needs and the projects you are working on. If you are using an older version of Python and you don’t need the new features or improvements, then there is no need to upgrade. However, if you are working on a project that requires the latest version of Python or the new features, then it is recommended to upgrade.
