A minimal Flask application looks something like this:
from flask import Flask
app = Flask(__name__)
@app.route("/")
def index():
return "Hello World!"
A large Flask application can separate one file into multiple files by blueprints.
Purpose
Make it easier for ...
let doc = require('dynamodb-doc');
let dynamo = new doc.DynamoDB();
var tblName = "MyTable";
exports.handler = (event, context, callback) => {
readOperation(context);
}
function readOperation(cnxt) {
var params = {
TableName: tblName,
Key: {

For a more real time solution you can use watchPosition function in Geolocation that notifies whenever an error or a position change occurs.
Unlike the getCurrentPosition the watchPosition returns an Observable

Things are easy when you have to use a C++ library in a Python project. Just you can use Boost.
First of all here is a list of components you need:
A CMakeList.txt file, because you're going to use CMake.
The C++ files of the C++ project.
The python file - this is your python project.

Assume the following enum:
enum Operation {
Multiply(left : Int, right : Int);
}
Enum matching can be performed as follows:
var result = switch(Multiply(1, 3)) {
case Multiply(_, 0):
0;
case Multiply(0, _):
0;
case Multiply(l, r):
l * r;
}

Assume the following structure:
var dog = {
name : "Woofer",
age : 7

Enum matching can be performed as follows:
var message = switch(dog) {
case { name : "Woofer" }:
"I know you, Woofer!";
case _:
"I don't know you, so...

"Array matching", Haxe manual
The | operator can be used anywhere within patterns to describe multiple accepted patterns. If there is a captured variable in an or-pattern, it must appear in both its sub-patterns.
var match = switch(7) {
case 4 | 1: "0";
case 6 | 7: "1";
case _: "2";
...
It is also possible to further restrict patterns with guards. These are defined by the case ... if(condition): syntax.
var myArray = [7, 6];
var s = switch(myArray) {
case [a, b] if (b > a):
b + ">" +a;
case [a, b]:
b + "<=" +a;

Extractors are identified by the extractorExpression => match expression. Extractors consist of two parts, which are separated by the => operator.
The left side can be any expression, where all occurrences of underscore _ are replaced with the currently matched value.
The right side is a p...
This relies on the official consul docker image to run consul in clustered mode in a docker swarm with new swarm mode in Docker 1.12. This example is based on http://qnib.org/2016/08/11/consul-service/. Briefly the idea is to use two docker swarm services that talk to each other. This solves the pro...
