The CoreFoundation APIs provide the CFSet and CFMutableSet types for use in C. Python has built-in set and frozenset types since 2.4, and since Python 3.0 and 2.7, supports non-empty set literals using a curly-bracket syntax, e.g.: {x, y, z}; empty sets must be created using set(), because Python uses {} to represent the empty dictionary.
When it is useful to sub-divide these sections (for example, to separate a list of magazine articles from a list of books), this should be done using level 3 headings (===Books===) instead of definition list headings (;Books), as explained in the accessibility guidelines.
The only required argument. Type it in, or use variables like {{FULLPAGENAME}}, (but not subpage linking with ../). 2: Section Label ("labeled section"), or heading (section title), to transclude. Optional parameter. If a label, it must have been added and saved first. 3: Range: Final section in a contiguous series of headings or labels to ...
This template is used to produce a heading when wikitext (e.g. ==Heading==) won't work. Headings will be added to the table of contents like normal headings. Template parameters [Edit template data] This template prefers inline formatting of parameters. Parameter Description Type Status Heading content 1 The name of the (sub)section this heading represents String required Heading size 2 A ...
In all versions of Python, boolean operators treat zero values or empty values such as "", 0, None, 0.0, [], and {} as false, while in general treating non-empty, non-zero values as true. The boolean values True and False were added to the language in Python 2.2.1 as constants (subclassed from 1 and 0 ) and were changed to be full blown ...
A list may contain the same value more than once, and each occurrence is considered a distinct item. A singly-linked list structure, implementing a list with three integer elements. The term list is also used for several concrete data structures that can be used to implement abstract lists, especially linked lists and arrays. In some contexts ...
[37] [38] Exchange sort works by comparing the first element with all elements above it, swapping where needed, thereby guaranteeing that the first element is correct for the final sort order; it then proceeds to do the same for the second element, and so on. It lacks the advantage that bubble sort has of detecting in one pass if the list is ...
A more involved example is the Boom hierarchy of the binary tree, list, bag and set abstract data types. [10] All these data types can be declared by three operations: null, which constructs the empty container, single, which constructs a container from a single element and append, which combines two containers of the same type. The complete ...
