In this example, power() gets the value of exponent from the outer function, generate_power(). Here’s what Python does when you call generate_power(): Define a new instance of power(), which takes a single arg
While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of Python that you might be unaware of. I find it a nice way to learn the internals of a programming language, and I believe that you'll find it ...
This doesn't mean that recursion is simple. Recursion can definitely be mind-bending. But recursion ispossiblethanks to Python's call stack. You can walk through thatfactorialfunction call yourself withPython Tutor: Usingforloops instead of recursion ...
Here, we pass the class int as the first argument (callable) to .default_factory. This creates a defaultdict which has default value set to zero. This method can be useful for counting items in a given group of items. Passing Arguments to .default_factory in Python If we want to add ...
Now all the developers in the Snake Corporation can develop their many libraries separately and still include them in the snake_corp namespace. This does mean that all the developers need to make sure they create a snake_corp folder at the root of their project without an __init__.py ...
In other words, increasing temperature does not guarantee that the LLM will sample outputs from the probability distribution you expect (e.g., uniform random). Nonetheless, we have other tricks to increase output diversity. The simplest way is to adjust elements within the prompt. For example, ...
) -> Callable[[T], Comparable]: @dataclass(slots=True) class Key[T]: value: T def __lt__(self: Self, other: Self) -> bool: return cmp(self.value, other.value) return Key Python actually provides a cmp_to_key function in the functools module which does just this. The return ty...
Or at least that's what it would tell Swift, if such code were actually legal – Swift 3.0 does not allow you to mix nested type with generics. Fortunately, this is exactly what Swift 3.1 allows, because nested types can now appear inside generic types. Not content to stop there, Swift...

Python does the following: Is there a__metaclass__attribute inFoo? If yes, create in memory a class object (I said a class object, stay with me here), with the nameFooby using what is in__metaclass__. If Python can't find__metaclass__, it will look for a__metaclass__at the ...
