How to change Python version to Python3.5 in labs

How can I change the default Python version in labs?

python3.5 command is not what I want.

I want a solution so that when I type python --version, it should result in 3.5


If you want to get python3.5 when you typed python --version.Open .bashrc add this line alias python=python3.5 save the file & use . ~/.bashrc command to apply these changes without re-login.
