Why is Python an Amazing Programming Language?
The introduction to Python language can help you understand why it is considered special. So, Python is an object-oriented high-level programming language. Guido van Rossum developed it and released it in 1991. It is highly popular for beginners due to its simplicity and readability and clear syntax. Also, new programmers can easily learn its concepts.
Python is preferred in different areas such as web development, mathematics, software creation, scripting, etc. It has the ability to integrate different components and has earned it the nickname “Glue Language.” Python is open-source in nature which means a large community of developers constantly makes its libraries and functionalities better.
Google, Instagram, Netflix, and Spotify use this popular programming language. It enables fast development and efficient execution. Moreover, Python is portable i.e. it allows code to be transferred across different platforms without errors and this aspect makes it a preferred choice among developers worldwide.
Why Checking Python Version is Important
As a Python developer or enthusiast, checking the version of Python installed on your system is crucial. Here are some reasons why:
- Compatibility: Different versions of Python have different features and capabilities, so it is essential to ensure that the version you are using is compatible with the libraries and frameworks you intend to use.
- Bug Fixes and Security Patches: New versions of Python come with bug fixes and security patches that address potential vulnerabilities and improve performance. It is crucial to keep up to date with the latest versions, so you don’t miss out on these vital updates.
- Support: Python has a vast community of developers who continue to add new features and develop new libraries, usually compatible with newer versions of Python. If you are using an older version, you may not receive support for some libraries and may not benefit from the latest advancements.
By keeping track of the Python version on your system, you can improve your project’s stability, security, and performance while keeping up to date with the latest features and libraries.
Command Line Method
The command line method is one of the quickest and most efficient ways to check the Python version installed on your system. This method is particularly useful for developers who are comfortable with executing commands.
To check the Python version using the command line, follow these simple steps:
- Open the command prompt on your system.
- Type the following command and press Enter: python –version
- The Python version installed on your system will be displayed, such as: Python 3.9.2
With these simple steps, you can easily check the Python version using the command line interface. This method works on both Windows and macOS operating systems.
Python Interactive Shell Method
Python interactive shell is a helpful tool for beginners and those who prefer a graphical user interface. Here is how you can check the Python version using the interactive shell:
- Open the Python interactive shell by typing “python” (without quotes) in your command prompt or terminal.
- Type the following command:
import sys - Next, type:
sys.version - The command prompt or terminal will display the version of Python installed on your system.
The output will look something like this:
3.9.1 (tags/v3.9.1:1dddb1086e, Dec 5 2020, 12:22:43) [MSC v.1927 64 bit (AMD64)]
Now that you know how to check Python version using interactive shell, you can easily determine if you need to update or install a specific version for your projects.
Check Python Version in Integrated Development Environments (IDEs)
If you are using an integrated development environment (IDE) for your Python projects, you can easily check the Python version installed on your system within the IDE’s interface. We will explore the steps to find the Python version in popular IDEs such as PyCharm, VS Code, and Jupyter Notebook.
PyCharm
In PyCharm, you can find the Python version by opening a Python file and navigating to Settings > Project: your_project_name > Python Interpreter. Here, you will find the version number displayed next to the Python interpreter.
VS Code
To check the Python version in VS Code, open a Python file and select the Python interpreter in the bottom left corner of the editor. The version number will be displayed next to the interpreter name.
Jupyter Notebook
In Jupyter Notebook, you can find the Python version by opening a new notebook and executing the following code in a cell:
import sys
print(sys.version)
The version number will be printed as the output of the code.
How to Check Python Version in Code
Checking the Python version programmatically is necessary for developers who want to ensure that their code is compatible with the specific version of Python their project requires. Here are a few examples of how to check the Python version using different programming languages and frameworks:
Python
To check the Python version using Python, you can use the following code:
import sys
print("Python version")
print(sys.version)
Java
For Java developers, you can use the following code to check the Python version:
Process p = Runtime.getRuntime().exec("python --version");
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
String version = in.readLine();
System.out.println(version);
JavaScript
If you want to check the Python version using JavaScript, you can use the following code:
var child_process = require('child_process');
child_process.exec('python --version', function (error, stdout, stderr) {
if(stdout) console.log('Python Version: ' + stdout);
if (error !== null) console.log('exec error: ' + error);
});
These are just a few examples of how to programmatically check the Python version. By using these codes, you can ensure that your project is running on the correct version of Python.
