How to use a specific version (something lower than 3.4) of python in jupyter notebook or google colab?

Question

I have to do data-analysis on brain data and there are some requirements that need to be met before I can load the data. One of the requirements is that my python version should be lower than 3.4. My group and I want to work on the code together in google colab but doing it in jupyter notebook initially is fine as well. I just can't find a way to run code with a lower python version. Without a lower version it just won't work. I know I can do !apt-get install python3.3 and that appears to work. When I call !python --version however, it still gives 3.7.12 as an output. How do I make sure I can run my code in an older version?

I'm not sure if you can achieve this in google colab. You can try to uninstall a version and then install the one you want.
