I'm sorry this question was closed. As I mentioned in my comments, I know about the other answers. I'm now convinced that there is no good answer. But this question was not a duplicate of previous questions and should not have been closed on those grounds.
When I run
import sys
print(sys.version)
I get 3.6.9 (default, Jul 17 2020, 12:50:27)
.
Is it possible to get colab to run a more recent version of Python?
