How to Check Version of Python

In today’s digital world, Python has emerged as one of the most popular programming languages, widely used for web development, data analysis, artificial intelligence, and more. Whether you are a beginner or an experienced developer, it is crucial to know the version of Python you are using. This knowledge can help you troubleshoot issues, choose the right libraries, and ensure compatibility with other software. In this article, we will guide you through various methods to check the version of Python on your system.

Using the Command Line

The most straightforward way to check the version of Python is by using the command line. Here’s how you can do it on different operating systems:

On Windows:

1. Open the Command Prompt by pressing `Win + R`, typing `cmd`, and pressing Enter.
2. Type `python –version` or `python -V` and press Enter.
3. The command line will display the version of Python you are using, for example, `Python 3.8.5`.

On macOS and Linux:

1. Open the Terminal by searching for it in the Applications folder or using the Command + Space shortcut.
2. Type `python –version` or `python -V` and press Enter.
3. The Terminal will show the version of Python, such as `Python 3.8.5`.

Using IDLE

If you are using Python’s integrated development environment (IDE), IDLE, you can check the version by following these steps:

1. Open IDLE.
2. In the interactive shell, type `import sys`.
3. Press Enter, and you will see the output `sys` followed by a series of attributes.
4. Look for the `version` attribute, which will display the version of Python you are using, such as `3.8.5`.

Using Jupyter Notebook

If you are working with Jupyter Notebook, you can check the Python version by executing the following command in a cell:

“`python
import sys
print(sys.version)
“`

This will display the version of Python, along with additional information such as the implementation and the platform.

Using pip

Another way to check the Python version is by using the `pip` package manager. Open the command line and type:

“`bash
pip –version
“`

This will show the version of `pip` installed on your system, which is usually the same as the Python version.

Conclusion

Knowing the version of Python is essential for developers to ensure compatibility and troubleshoot issues effectively. By using the methods outlined in this article, you can easily check the Python version on your system, whether you are using the command line, an IDE, or a notebook environment. Always keep an eye on the version to stay up-to-date with the latest features and improvements.
