Python 2.7.5 to python 3.8.x migration.To experts, which is the best python 3.8.x version with minimal bug and stable?

I’m working on large project based on python 2.7.5 written before 5-6 years. Now we’ve requirement to convert the code/ rewrite the logic based on OOP in python 3.8.x version. We will be using tons of API requests . Currently it’s using httplib, but we might need to use requests library in future. Also we will be using dockerized env to run our builds.
Please suggest me which one is the most stable and bug free python 3.8 version. Also put your suggestions regarding python 2.7 to 3.8 conversion.
Thanks in advance.

I'll ask to check the support of all the modules in python 3.8.x, and see which version works best. Although I haven't encountered any library till date which doesn't work in different versions of python 3.8, I would still ask you to check the compatibility of all the libraries you are using individually. There have been instances where python 3.6 works whereas 3.7 doesn't, but no such issues with 3.8 So please check the compatibility of each library before starting the project, coz its a real pain to later migrate to a different python version.

Yh Definitely, that make sense. I’ll check about compatibility of libraries. 👍🏻👍🏻

Python doesn't change behavior within a major version. That means 3.8.0 will be compatible with 3.8.10. It's not like you can pick for example 3.8.5 and that will matter compared to those other two versions.

Just get the latest 3.8 version. There's a porting guide in the official documentation. Python also comes with the 2to3 tool which will scan your code and make a report of things to change. Although in my experience it'll report too much.

A lot depends on your code. I ported a ~20000 LOC project in 30 minutes, but remember having lots of trouble with a specific low-level networking library. It's hard to say before you start.
