App Engine offers you a choice between two Python language environments. Both
environments have the same code-centric developer workflow, scale quickly and
efficiently to handle increasing demand, and enable you to use Google’s proven
serving technology to build your web, mobile and IoT applications quickly and
with minimal operational overhead. While the two environments have a lot in
common, they differ in a few important ways.
Choose your preferred environment
Python 2.7, Python 3.7, Python 3.8, Python 3.9, Python 3.10, and Python 3.11
