I would like to know the Python version of Google Colab as of December 2021.

Thank you for your cooperation in browsing and commenting.
I was able to solve myself this time.

Regarding the Python version of google-collective at the time of December, I found that it is very likely to be 3.7.12.

The Python version was 3.7.11 as of August 22nd last year, but now it is 3.7.12 and many of the blog and other information I referenced was 3.7.12 as of October and November, so I think it is 3.7.12

This will be the current Python version of Google-collection.

Also, the following are the blogs that I referred to.
From the four blog posts and current Python versions, we concluded that the figure was 3.7.12 as of December.
I think the information in December will be relatively reliable because the people who write on each blog are considered different.

Reference 1 (as of August last year)
Reference 2 (as of November last year)
Reference 3 (as of October last year)
Reference 4 (as of November last year)
