When you open the Python Interpreter by entering ‘python’ or ‘py’, it shows the version right away. For detailed version info, such as minor and micro numbers, use ‘import sys’ and ‘print(sys.version)’ or ‘print(sys.version_info)’.

For a quick look at the major and minor version, there’s a simple command. Use ‘import sys; print(‘{0[0]}.{0[1]}’.format(sys.version_info))’ right from the command line.

Verifying Installation Paths

To find where Python is installed on Windows, use the command ‘where python’. You’ll see the path, like ‘C:\PythonXX’, which helps if you have multiple installations.

Action Command Description
Check Python Version python --version Displays the Python version installed as the default interpreter.
List All Python Versions py -0p Lists all Python versions installed on the system with paths.
Access Python Interpreter python Opens the Python interpreter displaying the version on top.
Find Detailed Version Info import sys; print(sys.version) Provides comprehensive version information within the Python shell.
Locate Python Installation where python Reveals the directory paths to Python executables.

With these strategies, you can easily check your Python version. This ensures your development setup meets your project’s needs.

Verifying Your Python Version on Mac

For Mac lovers and programmers, knowing how to find your Python version is crucial. It helps you manage coding projects well. If you face problems or need to match a project with a specific Python version, becoming good at python version checking is beneficial. Start with a basic command in the Terminal to check.

First, open your Terminal found in the Utilities folder. Type

python –version

to see if you have Python 2.x. If you use Python 3.x, switch the command to

python3 –version

. This command will show your Python version, making it easy tocheck Python version

for your projects.

If you need more info, like for development or compatibility checks, start the Python shell. Use python or python3 to do this. Then, get all the details by running:

import sys

To leave the Python shell, type exit() or press Ctrl + Z.

  1. Open Terminal
  2. Enter python --version or python3 --version
  3. Start the Python environment:
    1. Type python or python3
    2. Run import sys; print(sys.version)
  4. Exit the Python shell with exit() or Ctrl + Z

This table gives you quick steps to check Python version on Mac:

Action Command Comment
