NPuzzle VS CPython

I'd love to get some feedback on python code/style https://github.com/mschrandt/NPuzzle

python has random.shuffle() and random.sample() with an MT Mersenne Twister PRNG for random. https://docs.python.org/3/library/random.html#random.shuffle Modules/_randommodule.c: https://github.com/python/cpython/blob/main/Modules/_randomm... , Library/random.py: https://github.com/python/cpython/blob/main/Lib/random.py#L3...

Python

Python bytecode is like a secret language that Python uses behind the scenes. When you write your Python code, it doesn’t run directly. Instead, Python translates your code into bytecode, a set of instructions that the Python interpreter can understand and execute.

Ensure you have Python installed on your system. You can download it from the official Python website. Verify the installation by running:

We strongly encourage maintainers of third-party Python projects to test with 3.13 during the beta phase and report issues found to the Python bug tracker as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (Tuesday 2024-07-30). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.13.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.13 as possible during the beta phase.

Before diving into Tkinter, ensure that you have Python installed on your computer. Visit the official Python website (https://www.python.org) and download the latest version suitable for your operating system.

I think there's a bit of a misunderstanding regarding exit. exit is not a keyword or a REPL command; it's actually a function exposed in the builtin package. you can run "import builtins; builtins.exit()"

To clarify, there are two things here: why exit exists in the REPL, and why it's a function. The exit() function is available only in the REPL, and it appears built-in, but it isn't part of the built-in namespace. Instead, exit is loaded automatically by the site module.

Heres is the code with the function site.main that is doing it: https://github.com/python/cpython/blob/8af84b503d0b62a3db0d8...

The line builtins.exit = _sitebuiltins.Quitter('exit', eof) shows that exit is set as a function. The Quitter class, which exit is an instance of, has a __call__ method, making it callable, so it as a function.

I don't believe you're wrong not understanding it; it's just that the process isn’t typically explained in detail, especially what happens when you start the REPL. This is why the message "Use exit() instead..." exists in the REPL: it needs that clarification.

In a nutshell, exit is a function loaded into the built-ins by the site.py module, which automatically activates when the REPL starts. This automatic loading is what makes exit, help, __copyright__ and others available only in the interactive sessions.
