Python version check

To check which version of Python is currently installed on your system, you can use the following command in the command line or terminal:

python --version         

or

python -V         

This will display the version number of Python that is currently being used.

Alternatively, you can check the version of Python in a script by using the sys module and accessing the version attribute of the sys.version

import sys print(sys.version)         

This will print the version number as well as additional information about the build and platform.

It's also worth noting that if you have multiple version of python installed you can use python3 --version or python2 --version to check the version of specific python version.

Another way to check the version of Python is by using the built-in platform module, which provides information about the platform where the Python interpreter is running. You can use the python_version() function to check the version of Python:

import platform print(platform.python_version())         

It is also good practice to include the version check in your script as a sanity check, so that you can ensure that the script is running on the correct version of Python.

Additionally, many modern text editor and Integrated Development Environment (IDE) have a built-in functionality to check the python version and switching between different version installed on your system.

It's always a good idea to check the version of python you're working with, especially if you're working on a project with multiple contributors. This will help ensure that everyone is using the same version of Python, avoiding any compatibility issues.
