In any topological space X, the empty set is open by definition, as is X. Since the complement of an open set is closed and the empty set and X are complements of each other, the empty set is also closed, making it a clopen set. Moreover, the empty set is compact by the fact that every finite set is compact. The closure of the empty set is empty.
A link to a "non-existing" category page is treated as a link to a non-existing page, even if the category is non-empty. A link to a "non-existing" local image page of an image on Commons is treated as a link to an existing page, e.g. Image:Cow-on pole, with horns.jpeg, except in the case of a link from an edit summary or log. An indication of ...
It supports macOS including Apple Silicon-based. It's a free compiler, though it also has commercial add-ons (e.g. for hiding source code). Numba is used from Python, as a tool (enabled by adding a decorator to relevant Python code), a JIT compiler that translates a subset of Python and NumPy code into fast machine code.
In computing, a minimal reproducible example (abbreviated MRE) [1] is a collection of source code and other data files which allow a bug or problem to be demonstrated and reproduced. The important feature of a minimal reproducible example is that it is as small and as simple as possible, such that it is just sufficient to demonstrate the ...

The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2] Software engineer Tim Peters wrote this set of principles and posted it on the Python mailing list in ...
In object-oriented computer programming, a null object is an object with no referenced value or with defined neutral (null) behavior.The null object design pattern, which describes the uses of such objects and their behavior (or lack thereof), was first published as "Void Value" [1] and later in the Pattern Languages of Program Design book series as "Null Object".
Maintenance template to be placed in sections that are empty, containing neither text nor sub-sections. Before tagging an empty section, consider removing the section heading instead – for example, an empty "Gallery", "See also" or "External links" section can safely be deleted. Puts articles into [[Category:Articles with empty sections]] and [[Category:Articles to be expanded]]. Template ...
