How to Check Python Version in Linux & Windows

Python is a versatile programming language, popular among developers, data scientists, and researchers. Its simplicity and extensive libraries make it ideal for web development, data analysis, AI, and machine learning.

Why Check the Python Version?

Checking your Python version ensures compatibility with libraries and projects. It helps avoid errors, makes sure you’re using the right version for development, and can help troubleshoot installation issues.

How to Check Python Version

1. Using Command Line

python --version
# or
python3 --version

This is the quickest way to check. Use `python3` if you specifically need to check Python 3.x version.

2. Using Python Shell

import sys
print(sys.version) # Shows full version with build info
print(sys.version_info) # Shows version as structured tuple

This method gives you more detailed information, including build numbers and compilation details.

3. Windows-Specific Commands

py --version # Shows default Python version
py -0 # Lists ALL installed Python versions
py -3 # Runs latest Python 3 version

The Python Launcher (`py`) in Windows makes it easy to manage multiple Python versions.

4. Check Installation Location

• Linux: which python3
• Windows: where python

These methods will help you quickly find the Python version on your system, whether you’re using Linux or Windows. Choose the method that works best for you to get the details you need.
