may help you . Python Part
SO can you have two different instances of (say) a string of "Bob" and have them not return true when compared using 'is'? Or is it infact the same as ===?
code :
a = "Bob"
b = "{}".format("Bob")
print a, b
print a is b, a == b
Bob Bob
False True
print 3 is 2+1
print 300 is 200+100
7. Return true if x and y refer to the same object. Otherwise, return false.

Websocket (javascript) vs Silverlight (ruby, python, javascript, c# etc)?

will help you WebSockets consists of parts: server and client. The server could be written in any language while the client is intended to be javascript. Using Ruby/Python on the client side is not possible unless you write a browser plugin capable of running this code (the way Silverlight does it).
Silverlight is .NET meaning that you could use any language capable of compiling into MSIL (C#, VB.NET, IronRuby, IronPython, ...) which will run inside the client browser using a plugin that needs to be installed.

may help you . What you're referring to is basically a printf / String.Format-like operation. Unfortunately, JavaScript currently does not have any built-in way of doing this (which is too bad, really).
There are, of course, many libraries that give this kind of functionality.
How to pass an argument which exceeds length of 4000 from Javascript to Python using python shell

How to pass an argument which exceeds length of 4000 from Javascript to Python using python shell

will help you The command line has a maximum size, which depends on your OS (and possibly your settings).1 That command line has to be enough to fit the name of the Python interpreter, and your script path, and the -u, and all of your (properly quoted) args. It's probably 4096 on your system, so when you have around 4000 characters worth of arguments, things start failing.
There are two general solutions to this.
code :
import sys
for arg in sys.argv[1:]:
    print('arg:', arg)
import sys
for line in sys.stdin:
    print('arg:', line, end='')
var options = {          
        pythonOptions: ['-u'],
        scriptPath: 'myscript.py',

myscript = new PythonShell(options);
var results = [];
myscript.on('message', function(message)) {
    results += [message];
for (var i in args) {
    myscript.send(args[i] + '\n');
myscript.end(function(err, code, signal) {    
    if (err) throw err;
    for (var k in results){
import sys
filename = sys.argv[1]
with open(filename) as f:
    for line in f:
        print('arg:', line, end='')
tempFile = new IDontRememberHowToSecurelyMakeATempFileInNode();
for (var i in args) {
    tempFile.write(args[i] + '\n');

var options = {          
    pythonOptions: ['-u'],
    scriptPath: __dirname,
    args: [tempFile.howeverYouGetTheFileName()]

PythonShell.run("../../../../extras/script/printer.py", options, function (err, results) {
    if (err) throw err;
    for(var k in results){

I wish this help you I'm a Python programmer, and learning how to write clean codes in JavaScript. I want to replicate the following python code using Javascript code: , For the first one, the function you're looking for is .map:
code :
const arr = [ { data: 'foo' }, { data: 'bar' } ];
  arr.map(({ data }) => data)
const someDict = {'key_1': [0,1], 'key_2': [3,4], 'key_3': [5,6]};
const result = Object.entries(someDict).reduce(
  (a, [key, [v0, v1]]) => {
    a[0][key] = v0;
    a[1][key] = v1;
    return a;
