Announcing configurable Python versions in Netlify builds

Netlify now supports configurable Python versions in builds, allowing users to specify the desired version through the PYTHON_VERSION environment variable. This feature enables developers to use any version of Python for their projects, accommodating legacy projects requiring older Python versions or taking advantage of new features in Python 3.x. By defining the Python version via the PYTHON_VERSION environment variable, users gain more control over their build environments and can ensure builds are optimized for their needs.
