How to check Python version in shell script?

Python is a high-level general-purpose programming language created by Guido van Rossum. It was first released in 1991. Usually, Linux-based distributions already come with a pre-installed version of Python.

This tutorial will help you find the Python version details in your script. Additionally, you can ensure that your Python script only runs the smallest version found.

import sys
print(sys.version)

Output:

3.5.2 (default, Nov 12 2018, 13:43:14)
[GCC 5.4.0 20160609]

You can also find detailed version information using sys.version_info as shown below:

>>> sys.version_info
 
sys.version_info(major=3, minor=5, micro=2, releaselevel='final', serial=0)

Show details of Python hex version . This value increases with each release of python.

>>> sys.hexversion
 
50660080

Using Assert in Python

You can ensure that your script runs with the minimum version required by your application. For example, a Python application will terminate if it is running a lower version of the Python interpreter than required. Add the following code to your application:

assert sys.version_info >= (3, 5)
