Switching between Python 2.x and 3.x in Linux machine

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1788 / 1 Year ago, fri, april 28, 2023, 5:59:12

I am having two code bases build_2.x and build_3.x which were coded in python 2.x and python 3.x respectively.

I have a Linux machine in which Python 2.x is installed, but for my project purpose I need to execute both builds in same machine.

How to run build_2.x and build_3.x separately?

Do I run the the build_2.x first, then should I update Pthon to 3.x after I need to run build_3.x?

And also what is the function of virtualenv in this case?

There are two programs to translate Python code to/from Python 2 and Python 3, 2to3 and python3-3to2. 2to3 is installed by default and python3-3to2 can be installed by the following command:

sudo apt install python3-3to2

To convert a file named example.py run the following commands:

2to3 -w example.py # translates Python 2 code to Python 3 code

or

3to2 -w example.py # translates Python 3 code to Python 2 code
