That doesn\u2019t make it supported. <strong>Python 2.7 officially reached end of life (EOL) on January 1, 2020, per the Python Software Foundation\u2019s <a href=\"https:\/\/peps.python.org\/pep-0373\/\" target=\"_blank\" rel=\"noreferrer noopener\">PEP 373<\/a>, and Python 2.x versions no longer receive support, security updates, or bug fixes from the official developers \u2014 so any active project belongs on a supported Python 3 release.<\/strong> The date wasn\u2019t a surprise, either: Python 3.0 first shipped on December 3, 2008, so the two lines coexisted for more than a decade before support for Python 2 finally ended.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Python 2.7 received a five-year support extension, moving its EOL date to 2020 \u2014 but that grace period is long gone. Since Ubuntu 22.04 (Jammy) and Ubuntu 24.04 (Noble), Python 2.7 is no longer included in the operating system, and Python 2.x versions are no longer available on servers running these releases. If your code still depends on Python 2, the ground it stands on is disappearing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This might seem like a daunting transition, especially if you\u2019ve been coding in Python 2.7 for a while.

If you\u2019re migrating from Python 2 in 2026, target a currently supported release: Python 3.13 or 3.14 gives your code the longest runway before the next upgrade.<\/p>\n\n\n\n<h2 id=\"h-python-vs-python3-what-s-the-difference\" class=\"wp-block-heading\">Python vs. python3: what\u2019s the difference?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">They\u2019re commands, not different languages; the question is which interpreter each one launches on your system. During the years when Python 2 and Python 3 had to coexist, <a href=\"https:\/\/peps.python.org\/pep-0394\/\" target=\"_blank\" rel=\"noreferrer noopener\">PEP 394<\/a> recommended that <code>python2<\/code> run a Python 2 interpreter and <code>python3<\/code> run a Python 3 interpreter, while the bare <code>python<\/code> command was left up to each distribution: it may point to Python 3, point to Python 2 on older systems, or not exist at all. That\u2019s why tutorials tell you to type <code>python3<\/code>, as it\u2019s the one name guaranteed to reach Python 3. Inside an activated virtual environment, plain <code>python<\/code> always runs that environment\u2019s interpreter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not sure what a command runs on your machine? Ask it: <code>python --version<\/code> or <code>python3 --version<\/code>.<\/p>\n\n\n\n<h2 id=\"h-why-upgrade-from-python-2\" class=\"wp-block-heading\">Why upgrade from Python 2?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Python 3 is the future, and it\u2019s here to stay. It introduces many improvements and new features that make coding in Python more efficient and enjoyable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-security-and-compatibility\">Security and compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The primary concern with continuing to use Python 2.7 (and other older versions) is security. Think of a post-EOL runtime as a building whose landlord has stopped doing repairs: everything keeps working until something breaks, and then no one is coming to fix it. Without ongoing updates and patches, any vulnerabilities discovered post-EOL pose a significant risk to applications and systems still running this version. Moreover, newer operating systems, such as Ubuntu 24.04 (Noble) and later, do not include Python 2.7 at all, creating additional challenges in terms of compatibility and future-proofing your infrastructure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-enhanced-features-and-improved-performance\">Enhanced features and improved performance<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Python 3 adds f-strings, async functions, modern type-checking tools, and improved memory management.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-what-actually-breaks-between-python-2-and-python-3\">What actually breaks between Python 2 and Python 3<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Python 3.0 was deliberately incompatible with the 2.x line: per <a href=\"https:\/\/www.python.org\/download\/releases\/3.0\/\" target=\"_blank\" rel=\"noreferrer noopener\">python.org\u2019s release notes<\/a>, \u201cmany details, especially how built-in objects like dictionaries and strings work, have changed considerably,\u201d deprecated features were removed, and the standard library was reorganized. These are the changes migrating code trips over most:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>What changed<\/th><th>Python 2<\/th><th>Python 3<\/th><\/tr><\/thead><tbody><tr><td>print<\/td><td>Statement: <code>print \"hello\"<\/code><\/td><td>Function: <code>print(\"hello\")<\/code><\/td><\/tr><tr><td>Division<\/td><td><code>5 \/ 2<\/code> returns <code>2<\/code><\/td><td><code>5 \/ 2<\/code> returns <code>2.5<\/code> (use <code>\/\/<\/code> for floor division)<\/td><\/tr><tr><td>Strings<\/td><td>Bytes by default, with a separate <code>unicode<\/code> type<\/td><td>Unicode by default, with a separate <code>bytes<\/code> type<\/td><\/tr><tr><td>User input<\/td><td><code>raw_input()<\/code><\/td><td><code>input()<\/code><\/td><\/tr><tr><td>Standard library<\/td><td>Python 2 module layout<\/td><td>Reorganized in prominent places, with renamed modules<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 id=\"h-preparing-for-the-transition\" class=\"wp-block-heading\">Preparing for the transition<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This whole process may seem daunting, but with the right resources and planning, this can be a smooth process. Here are some steps to guide you through the migration:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Audit Your Existing Python Codebase: <\/strong>Identify dependencies and third-party libraries that you\u2019re currently using. Check if they are supported in Python 3, and note any that need to be updated or replaced.<\/li>\n\n\n\n<li><strong>Check The Documentation:<\/strong> Familiarize yourself with the functional differences between Python 2.7 and Python 3. Resources like the <a href=\"https:\/\/docs.python.org\/3\/index.html\" target=\"_blank\" rel=\"noreferrer noopener\">official Python 3 documentation<\/a> will provide an excellent starting point.\u00a0<\/li>\n\n\n\n<li><strong>Use tools to automate migration:<\/strong> The classic converter, <a href=\"https:\/\/docs.python.org\/3.12\/library\/2to3.html\" target=\"_blank\" rel=\"noreferrer noopener\">2to3<\/a>, can automate much of the translation from Python 2.7 to Python 3. It handles straightforward changes like print statements, <code>raw_input()<\/code>, and renamed standard-library modules. One big caveat: 2to3 was deprecated in Python 3.11 and removed from the standard library in Python 3.13, so you\u2019ll need to run it under Python 3.12 or earlier. It also can\u2019t fix everything. Integer division changes, for example, are beyond it. AI coding assistants can also translate Python 2 code to Python 3 and draft test scaffolding, though their output needs the same thorough testing as any automated conversion.\u00a0<\/li>\n\n\n\n<li><strong>Test Thoroughly:<\/strong> After migrating your code, thorough testing is crucial. Ensure that your updated application performs as expected on Python 3. Unit tests, integration tests, and system tests can all help verify that the transition has not introduced new issues.<\/li>\n\n\n\n<li><strong>Plan For Deployment:<\/strong> Once your application is updated and tested, plan a rollout that minimizes downtime. Consider deploying in stages or using canary releases to mitigate risks.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Transitioning your Python 2.x code to Python 3 might seem like a Herculean task, but the Python community has got you covered. The official Python documentation now collects porting resources (the archived original porting guide plus maintained third-party guides from Fedora, DigitalOcean, and ActiveState) on its <a href=\"https:\/\/docs.python.org\/3\/howto\/pyporting.html\" target=\"_blank\" rel=\"noreferrer noopener\">\u201cHow to port Python 2 Code to Python 3\u201d<\/a> page.<\/p>\n\n\n\n<h2 id=\"h-what-if-you-can-t-migrate-yet\" class=\"wp-block-heading\">What if you can\u2019t migrate yet?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes the blocker isn\u2019t your code. It\u2019s a critical dependency or vendor application that never got a Python 3 port. If that\u2019s you, limit the risk while you work the problem:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Isolate the legacy workload.<\/strong> Run the Python 2.7 application in its own container or virtual machine, off the public internet, so an unpatched vulnerability can\u2019t reach the rest of your infrastructure.<\/li>\n\n\n\n<li><strong>Replace the blocking dependency.<\/strong> An abandoned Python 2 library may have a maintained Python 3 successor or fork \u2014 check PyPI before assuming you\u2019re stuck.<\/li>\n\n\n\n<li><strong>Port just the blocker.<\/strong> If the dependency is small and open source, porting it yourself can be cheaper than living with an unsupported stack.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Treat all of these as stopgaps with an end date, not a destination: the repairs aren\u2019t coming, and every day on Python 2.7 is another day without security patches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While saying goodbye to Python 2.x may be bittersweet for many, the transition to Python 3 is both necessary and beneficial. With improved functionality, enhanced security, and continued support, Python 3 is well-prepared to champion the next generation of development.<\/p>\n\n\n\n<h2 id=\"h-how-do-i-run-python-3-on-dreamhost\" class=\"wp-block-heading\">How do I run Python 3 on DreamHost?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Python 3 is ready to go: DreamHost installs Python on all of its servers by default, and DreamHost servers run Ubuntu LTS releases \u2014 Python 2.7 is no longer available on servers running Ubuntu 22.04 (Jammy) or 24.04 (Noble), per DreamHost\u2019s <a href=\"https:\/\/help.dreamhost.com\/hc\/en-us\/articles\/216137717-Python-overview\" target=\"_blank\" rel=\"noreferrer noopener\">Python overview<\/a> and <a href=\"https:\/\/help.dreamhost.com\/hc\/en-us\/articles\/26139217919380-Preparing-for-Ubuntu-Noble\" target=\"_blank\" rel=\"noreferrer noopener\">Ubuntu Noble<\/a> knowledge base articles (updated July 2026).
