Consider the case of creating a nested list structure by multiplying: li = [[]] * 3 print(li) # Out: [[], [], []] At first glance we would think we have a list of containing 3 different nested lists. Let's try to append 1 to the first one: li[0].append(1) print(li) # Out: [[1], [1], [1]] ...

Use in operator to check if an element is a member of a list. iex> 2 in [1, 2, 3] true iex> "bob" in [1, 2, 3] false

Looping via recursion is also possible in Kotlin as in most programming languages. fun factorial(n: Long): Long = if (n == 0) 1 else n * factorial(n - 1) println(factorial(10)) // 3628800 In the example above, the factorial function will be called repeatedly by itself until the given conditio...

The Kotlin Standard Library also provides numerous useful functions to iteratively work upon collections. For example, the map function can be used to transform a list of items. val numbers = listOf(1, 2, 3, 4, 5, 6, 7, 8, 9, 0) val numberStrings = numbers.map { "Number $it" } One of...

Use Conditionals via (syntax is in [brackets]): when [when:] Task: - name: run if operating system is debian command: echo "I am a Debian Computer" when: ansible_os_family == "Debian" loops [with_items:] loops [with_dicts:] Custom Facts [ wh...

Basic Usage Use the when condition to control whether a task or role runs or is skipped. This is normally used to change play behavior based on facts from the destination system. Consider this playbook: - hosts: all tasks: - include: Ubuntu.yml when: ansible_os_family == "Ubunt...

Ordering the results and setting a limit can easily be achieved with 2 additional lines added to the chain, like so: $db = JFactory::getDbo(); $query = $db->getQuery(true); $query->select('*') ->from('#__users') ->where('username = '. $db->q('John')) ->ord...

A simple query that selects all users from the #__users table with a username that matches John $db = JFactory::getDbo(); $query = $db->getQuery(true); $query->select('*'); $query->from('#__users'); $query->where('username = '. $db->q('John')); $db->setQuery($query); ...

Directives can be used to build reusable components. Here is an example of a "user box" component: userBox.js angular.module('simpleDirective', []).directive('userBox', function() { return { scope: { username: '=username', reputation: '=reputation' }, ...
