Python version shipping with Mac OS X Snow Leopard смотреть онлайн

Mac OS X Snow Leopard, also known as Mac OS X 10.6, was released by Apple in August 2009. It shipped with Python 2.6.1 pre-installed. Python 2.6 was a significant improvement over Python 2.5, introducing many new features, bug fixes, and performance enhancements. In this tutorial, we'll explore how to use Python 2.6 on a Snow Leopard system and provide a code example.
Note: Python 2.6 is outdated and no longer supported. It's highly recommended to use a more recent Python version for any new projects or development work. The tutorial focuses on Python 2.6 for historical reference.
To check which Python version is installed on your Snow Leopard system, open the Terminal and run the following command:
You should see an output like this:
This confirms that Python 2.6.1 is installed and available on your system.
To run Python 2.6, you can simply enter the python command in the Terminal. Here's an example of running a Python script:
Save this code to a file, for example, hello.py, and then run it in the Terminal:
You should see the output:
Python 2.6 has a comprehensive standard library that includes modules for various tasks. Here's a quick example of using the math module to calculate the square root of a number:
Save this code to a file, run it with Python, and you'll see the square root of 16 displayed on the screen.
Python 2.6 allowed you to install third-party packages using tools like easy_install. For example, to install the requests library, you could run:
This will download and install the requests library, allowing you to make HTTP requests in your Python 2.6 code.
While Python 2.6 does not have the built-in venv module, you can create virtual environments using the virtualenv tool, which can be installed as follows:
Then, create a virtual environment:
Activate the environment:
Now, you can install packages specific to your project within this isolated environment without affecting the system-wide Python.
Python 2.6, shipped with Mac OS X Snow Leopard, was a reliable and capable version of Python for its time. However, it's essential to note that Python 2.6 is no longer supported and is considered outdated. For new projects and development work, it is strongly recommended to use a more recent Python version, such as Python 3.x, to take advantage of the latest features, security updates, and a broader ecosystem of packages and libraries.
