Similar to other programming, markup, and markdown languages, comments in HTML provide other developers with development specific information without affecting the user interface. Unlike other languages however, HTML comments can be used to specify HTML elements for Internet Explorer only. This topi...

Define a function with the function keyword: function f { } Define a function with (): f(){ } Define a function with both the function keyword and (): function f(){ }

Conditional expressions, involving keywords such as if, else if, and else, provide Swift programs with the ability to perform different actions depending on a Boolean condition: True or False. This section covers the use of Swift conditionals, Boolean logic, and ternary statements. For more in...

Scala has first-class functions. Difference between functions and methods: A function is not a method in Scala: functions are a value, and may be assigned as such. Methods (created using def), on the other hand, must belong to a class, trait or object. Functions are compiled to a class exte...

Not all elements of the XML input will end up as elements of the parsed tree. Currently, this module skips over any XML comments, processing instructions, and document type declarations in the input. Nevertheless, trees built using this module’s API rather than parsing from XML text can have comm...

There are many situations where it is useful to return several values from a function: for example, if you want to input an item and return the price and number in stock, this functionality could be useful. There are many ways to do this in C++, and most involve the STL. However, if you wish to avoi...

Strings are objects that represent sequences of characters. The standard string class provides a simple, safe and versatile alternative to using explicit arrays of chars when dealing with text and other sequences of characters. The C++ string class is part of the std namespace and was standardized i...

In Node.js, resource intensive operations such as I/O are performed asynchronously, but have a synchronous counterpart (e.g. there exists a fs.readFile and its counterpart is fs.readFileSync). Since Node is single-threaded, you should be careful when using synchronous operations, because they will...

Kotlin is a statically-typed object-oriented programming language developed by JetBrains primarily targeting the JVM. Kotlin is developed with the goals of being quick to compile, backwards-compatible, very type safe, and 100% interoperable with Java. Kotlin is also developed with the goal of prov...

Use context processors to add variables that are accessible anywhere in your templates. Specify a function, or functions that return dicts of the variables you want, then add those functions to TEMPLATE_CONTEXT_PROCESSORS.

empty_set = set() # initialize an empty set literal_set = {'foo', 'bar', 'baz'} # construct a set with 3 strings inside it set_from_list = set(['foo', 'bar', 'baz']) # call the set function for a new set set_from_iter = set(x for x in range(30)) # use arbitrary iterables to create a set set_f...

The built-in collections package provides several specialized, flexible collection types that are both high-performance and provide alternatives to the general collection types of dict, list, tuple and set. The module also defines abstract base classes describing different types of collection functi...
