There are two functions that can be used to obtain a readable representation of an object. repr(x) calls x.__repr__(): a representation of x. eval will usually convert the result of this function back to the original object. str(x) calls x.__str__(): a human-readable string that describes the obje...
A simple example of using multiple processes would be two processes (workers) that are executed separately. In the following example, two processes are started: countUp() counts 1 up, every second. countDown() counts 1 down, every second. import multiprocessing import time from random impor...

HashMap is an implementation of the Map interface that provides a Data Structure to store data in Key-Value pairs. 1. Declaring HashMap Map<KeyType, ValueType> myMap = new HashMap<KeyType, ValueType>(); KeyType and ValueType must be valid types in Java, such as - String, Integer, Fl...
To ensure that our collection can be iterated using iterator or for-each loop, we have to take care of following steps: The stuff we want to iterate upon has to be Iterable and expose iterator(). Design a java.util.Iterator by overriding hasNext(), next() and remove(). I have added a simple ...
Here's how to match a prefix code (a + or (00), then a number from 1 to 1939, with an optional space): This doesn't look for a valid prefix but something that might be a prefix. See the full list of prefixes (?:00|\+)?[0-9]{4} Then, as the entire phone number length is, at most, 15, we can look...
Read the accelerometer Sensor with precision. This example allocates memory: void Update() { //Get Precise Accelerometer values Vector3 accelValue = preciseAccelValue(); Debug.Log("PRECISE X: " + accelValue.x + " Y: " + accelValue.y + " Z: " + acc...
Angular 2 offers two different types of pipes - stateless and stateful. Pipes are stateless by default. However, we can implement stateful pipes by setting the pure property to false. As you can see in the parameter section, you can specify a name and declare whether the pipe should be pure or not, ...
int n = 0; while (n < 5) { Console.WriteLine(n); n++; } Output: 0 1 2 3 4 IEnumerators can be iterated with a while loop: // Call a custom method that takes a count, and returns an IEnumerator for a list // of strings with the names of theh largest city metro areas. ...
A For Loop is great for doing things a certain amount of time. It's like a While Loop but the increment is included with the condition. A For Loop is set up like this: for (Initialization; Condition; Increment) { // Code } Initialization - Makes a new local variable that can only be us...
It is similar to a while loop, except that it tests the condition at the end of the loop body. The Do - While loop executes the loop once irrespective of whether the condition is true or not. int[] numbers = new int[] { 6, 7, 8, 10 }; // Sum values from the array until we get a total that's ...
// Print the multiplication table up to 5s for (int i = 1; i <= 5; i++) { for (int j = 1; j <= 5; j++) { int product = i * j; Console.WriteLine("{0} times {1} is {2}", i, j, product); } }
Constants in Go may be typed or untyped. For instance, given the following string literal: "bar" one might say that the type of the literal is string, however, this is not semantically correct. Instead, literals are Untyped string constants. It is a string (more correctly, its default ...
