The Python team will not upgrade or provide any support for the 2.x versions of Python, even if someone finds a security issue in it.

As long as your project is working fine and is free from security issues, why worry? Anaconda makes it easy to maintain your Python 2.7 environment so you can continue to run that software in the future. You can even have multiple projects in both P2 and P3 and manage them easily in different &#8220;.conda&#8221; environments. However,&nbsp; Python 3 rectifies some fundamental design flaws and redundancies which should lead to more simple and elegant code. But this also means that Python 2.x code isn\u2019t automatically compatible with Python 3. Migrating from Python 2.x to version 3 needs to be done.<br><\/p>\n\n\n\n<p>Why should we migrate to Python 3? When we start a new project from scratch, begin with Python 3. This way, you can access many additional features which are not available on Python 3. If your legacy project relies heavily on features that are different in Python 3, then migrate. For example, Python 3 changes how strings are handled, making Unicode strings the default. This provides better support for accented characters, foreign languages and various other applications. If your application depends on robust handling of international characters, consider migrating to Python 3. It will be very hard to maintain the code which works on 2 versions of python. If your project relies on popular packages like Scikit-learn that have announced plans to drop Python 2 support and if you are concerned with security vulnerabilities, make it a priority to migrate to Python 3. Python 2 has stopped the support to the same.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h1 class=\"wp-block-heading\"><strong>Is the migration hard?<\/strong><\/h1>\n\n\n\n<p>Migrating from Python 2 to 3 is not that hard. The most popular libraries have already migrated. If you have a large code base to migrate, survey your code for the key language differences between the 2 versions. That will help you understand the complexities you will have to face while migrating. The library &#8220;<a rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/pypi.org\/project\/six\/\" target=\"_blank\">Six<\/a>&#8221; provides utility functions for smoothing over the differences between Python 2 and 3, providing a handy compatibility library to help you understand the differences.<br><\/p>\n\n\n\n<p>If you are currently developing code that needs to run in both Python 2 and Python 3, you should be using: \u201cfrom __future__&nbsp; import print_function, absolute_import, division\u201c. This forces you to write code that\u2019s Python 3 friendly, at least concerning the `print`, `import`, and division statements.<br><\/p>\n\n\n\n<p>Trouble migrating your project?
