Python - *args and **kwargs

🐍 *args

Args in *args stand for arguments. It is not necessary to use args. You could name it anything. What is important is the asterisk. You could name the variable anything, but adding an asterisk in front of it, adds one awesome functionality to it. That is, it can take any number of arguments/variables from the user and save it in the form of a tuple in the variable args or whatever you might have named it.

Example

def test(*args):
    print(args)
    print(sum(args))


a = test(1,2,3,4,5)

**kwargs

Kwargs is similar to args, except it takes key-value pairs and not variables as arguments. Again, it is not necessary to name it kwargs. What is necessary is the two asterisks. It takes any number of key-value pairs and stores in a dictionary.

Example

def test(**kwargs):
    print(kwargs)

test(a=1, b=str(2), c='three')

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

If you are getting the error: Uncaught TypeError: firebase.database is not a function Resolve it by including firebase-database.js in your html page as follows: <!-- The core Firebase JS SDK is always required and must be listed first --> <script defer src = "https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js" ></script> <script defer src = "https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js" ></script> That is it.
