I have a dedicated web server which runs CentOS 6.6

I am running some script that uses Python SHA module and I think that this module is deprecated in the current Python version.

I am consider downgrading my Python installation so that I can use this module.

Is there a better option? If not, how should I do it?

These are my Python installation details:

I would be very wary downgrading your default python – Padraic Cunningham
i think itis not the default as it was working good but after updating yum this problem proceeds – ma5noo2
You can install another version of python using make altinstall toomuchdata.com/2014/02/16/how-to-install-python-on-centos If you screw with the default you will break your OS – Padraic Cunningham
And create a virtual environment that suits your purposes. – MasterAM

You can always install a different version of Python using the -altinstall argument, and then run it either in a virtual environment, or just run the commands with python(version) command.

A considerable amount of CentOS is written in Python so changing the core version will most likely break some functions.

Instead of literally downgrading, I would consider virtualenv. It lets you create isolated python environments, including the specific python version and the modules.
