In UTF-16, a BOM (U+FEFF) may be placed as the first bytes of a file or character stream to indicate the endianness (byte order) of all the 16-bit code units of the file or stream. If an attempt is made to read this stream with the wrong endianness, the bytes will be swapped, thus delivering the character U+FFFE , which is defined by Unicode as ...
The marker interface pattern is a design pattern in computer science, used with languages that provide run-time type information about objects.It provides a means to associate metadata with a class where the language does not have explicit support for such metadata.

Pytest's markers can, in addition to altering test behaviour, also filter tests. Pytest's markers are Python decorators starting with the @pytest. mark.< markername > syntax placed on top of test functions. With different arbitrarily named markers, running pytest -m <markername> on the command line will only run those tests decorated with such ...
The programmer might infer the meaning after reading the code carefully, but it is not obvious. [6] Magic numbers become particularly confusing when the same number is used for different purposes in one section of code. It is easier to alter the value of the number, as it is not duplicated.
Sometimes code contains a novel or noteworthy solution that warrants an explanatory comment. Such explanations might be lengthy and include diagrams and formal mathematical proofs. This may describe what the code does rather than intent, but may be useful for maintaining the code.
