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.
