How to See What Version of Python You Have?

Getting the Most Out of Your Python Installation

If you’re a Python developer, you’re likely familiar with the importance of having the latest version of the language installed on your computer. However, many developers and enthusiasts often wonder what version of Python they have installed, and how to determine it. In this article, we’ll guide you through the process of seeing what version of Python you have, and provide you with various methods to find and verify your Python installation.

Method 1: Check Your Command Line

The simplest way to see what version of Python you have is to check your command line. You can use the following commands to verify your Python version:

• Python –version: This command will display the version of Python you’re currently using.
• python -c "import builtin and builtins and print(builtins.version)": This command imports the built-in functions and modules of Python and prints the version of Python.
• python -c "import builtins and print(builtins.version)": This command imports the built-in functions and modules of Python and prints the version of Python.

Running these commands will display the version of Python you have installed on your computer.

Method 2: Use a Python Version Checker

If you don’t want to run these commands in the command line, you can use a Python version checker. A Python version checker is a tool that checks your Python installation and reports the version of Python you have. Here are a few options:

• pip3 -V: This command checks your pip version (which is Python 3.x) and reports the version of Python you have.
• py -V: This command checks your Python version and reports the version of Python you have.
• python -m pip version: This command checks your pip version (which is Python 3.x) and reports the version of Python you have.

Method 3: Check Your Python Library Installation

Another way to see what version of Python you have is to check your Python library installation. If you’re using a Python IDE like PyCharm, Visual Studio Code, or Spyder, you can check the version of the library you’re using.

• PyCharm: In PyCharm, you can check the version of the library you’re using by going to Tools > Version Control > Show Locations and looking for the version of the library.
• Visual Studio Code: In Visual Studio Code, you can check the version of the library you’re using by going to View > Command Palette > Search and typing Python: Check Library.
• Spyder: In Spyder, you can check the version of the library you’re using by going to Tools > Preferences > Python Interpreter and looking for the version of the library.

Method 4: Use a Command Line Tool

A command line tool is a small program that can be used to manipulate your Python installation. One popular tool is pyenv.

• Install pyenv: You can install pyenv using pip: pip install pyenv.
• Update pyenv: Once installed, you can update pyenv using the following command: pyenv update.
• Check your version: Once pyenv is installed, you can check your Python version by running: pyenv versions
• Check your Python version: You can also check your Python version by running: pyenv --version

Significant Changes in Python 3.10 and Later

If you’re using Python 3.10 or later, you’ll notice some significant changes in the language. Here are a few examples:

• Lambda functions: In Python 3.10 and later, lambda functions are renamed to Functions. For example: lambda x: x becomes def function(x): x
• Anonymous functions: In Python 3.10 and later, anonymous functions are renamed to Generator Expressions. For example: a = (x for x in range(10)) becomes a = (x for x in range(10))
• Type annotations: In Python 3.10 and later, type annotations are renamed to Type Hints. For example: def greet(name: str) -> None: pass becomes def greet(name: str) -> None: pass

Conclusion

In this article, we’ve provided you with a step-by-step guide on how to see what version of Python you have. From checking your command line to using a Python version checker, there are many ways to determine the version of Python you have. By following these steps, you’ll be able to get the most out of your Python installation and ensure that you’re using the latest version of the language.
