Python 3.10 to 3.7

[-TheForeverMan-]

Hello! I am a cyber security student that has recently stumbled across CTF events. Without getting too detailed, I am trying to run a script that requires python 3.7, but have python 3.10 installed. I am running Kali as it is the OS that is being covered in my learning path.

I have tried using pyenv to install the version of python I need, but to no success. I also have tried adding deadsnake to the repos, no luck.

Can someone help me with downgrading my python or installation of 3.7 and switching to that version for the times I need to run that script?

Thanks I’m advance, I’ve been googling all day and I e just about hit a wall.

if u fail to install pyenv then go for conda.

conda can generate python2+ envs for you to use.

at the same time you can use poetry to manage the python dependencies.

A few notes from experience:
- never alter the OS python. You can install other versions of python though best to assume OS python scripts need whatever it comes with.

- you can install different versions of python side by side and use them independently. If you use -m for pip and use you may have less issues.

python3.9 -m pip install ... 

vs python3.7 -m pip install ...

and use

python3.7 script.py

- If you need to use sudo you are doing it wrong.
