Python - Calculate Money Change and Denomination

🐍 Python program to calculate change and denominations. The user enters the price and then the amount of money given. The program will figure out the change and the number of ones, twos, fives, tens, twenties, fifties, hundreds, two hundreds, and thousands to be returned.

Use dictionary data type.

Solution

def changecalculator(bill, received):
    if received > bill:

        change_dic = {'thousand' : 0, 'fivehundred' : 0, 'twohundred' : 0, 'hundred' : 0, 'fifty' : 0, 'twenty' : 0, 'ten' : 0, 'five' : 0, 'two' : 0, 'one' : 0}

        changeof = received - bill
        rem = changeof
        print(f"Amount to be returned: {rem}")
        while rem > 0:
            if rem >= 1000:
                change_dic['thousand'] += rem//1000
                rem = rem%1000
                
            elif rem >= 500:
                change_dic['fivehundred'] += rem//500
                rem = rem%500
                
            elif rem >= 200:
                change_dic['twohundred'] += rem//200
                rem = rem%200
                
            elif rem >= 100:
                change_dic['hundred'] += rem//100
                rem = rem%100
                
            elif rem >= 50:
                change_dic['fifty'] += rem//50
                rem = rem%50
                
            elif rem >= 20:
                change_dic['twenty'] += rem//20
                rem = rem%20
                
            elif rem >= 10:
                change_dic['ten'] += rem//10
                rem = rem%10
                
            elif rem >= 5:
                change_dic['five'] += rem//5
                rem = rem%5
                
            elif rem >= 2:
                change_dic['two'] += rem//2
                rem = rem%2
                
            elif rem >= 1:
                change_dic['one'] += rem//1
                rem = rem%1
                
    return change_dic
    
if __name__ == '__main__':
    bill = int(input("Enter the bill amount: "))
    received = int(input("Enter the received amount: "))
    print(changecalculator(bill, received))

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.

Resolve: Uncaught TypeError: firebase.database is not a function

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. Let me know if this was helpful.
