Name Generators Blog

In this short tutorial I will show you how to make a random name generator in Python.

If you came here looking for some cool random names visit the online name generators.

The name generator script

Open IDLE which is the Python supplied IDE or editor (Go to the bottom of the post to see, how you get started with Python).

Open a new window from the file menu and write the following name generator script into this window.

def name_generator():
  import random
  color = ["Red","Blue","Black","White"]
  tool = ["Hammer","Drill","Cutter","Knife"]
  randomNumber1 = random.randrange(0,len(color))
  randomNumber2 = random.randrange(0,len(tool))
  name = color[randomNumber1] + " " + tool[randomNumber2]
  print(name)

name_generator()

(Be aware that copy-paste from the blog may give syntax errors!
 A correct indent is an important element Python syntax!)

Save it as name-generator.py.  Now you can run the python program by pressing F5.

Name generator walk through

Lets walk through the python script, line by line.

1. In the first line we define our name generator function.
2. Then we import the random module, so we can call the random function later on.
3. In line define 2 arrays (color and tool) and asign values to them
4. Then we make 2 random numbers based on the length of our arrays. The randrage() function returns an integer in the range defined by the parameters. As parameters we use 0 and the len() function to count the numbers of words in the arrays.
5. In line 7 and 8 we make the final name and print it on the screen.
6. Finally we call the name generator function, we have just written.

That’s all it takes to make a simple Python random name generator. When you this basic functionality it’s easy to experiment and develop the random name generator to suit your needs and wishes.

Name generator inspiration

For inspiration visit the name generators where you can find a lot of name generators in several genres. From random names over fantasy and nicknames to band and business names.

Python Beginner guides and tutorials

Python is a free scripting language running on all platforms from Linux to Windows. Python is a relative easy programming language and a name generator is a simple application so it’s a good place to start if you wanna learn some programming.

If you haven’t Python installed at your computer you can download it at Python.org. This name generator script is based on python 3.12, which is the newest stable version at the moment.

At python.org you can find an excellent Python tutorial. And you can find much more about how to use the Random function in Python.

Or visit this beginner guide to Python which contains lots of links and resources.

I continue to give away stuff.  This time it’s a name generator widget.

The name generator widget integrates seamlessly with the web site. The widget contains all the necessary code to run very easily on a web page. Just add a single line of code to your page.

The name generator widget makes code names, that can be used in various ways.  Use the  widget to make code names for bands, projects, blog names etc.

See how the widget works at my sidebar. —–>

How to install the widget

Just insert this line of simple  code, where you want the  name generator to run, and you got a fully functional name generator on your site.

<script type=”text/javascript” src=”http://name-generators.com/widgets/name-generator-widget-beta.js”></script>

The widget takes care of the rest. From name generation to styling.

How to customize the name widget.

Use firebug or other developer tool to see the unique id’s and classes on  all elements.  Just add these to your style sheet with the styles you want. In this way it’s easy to add background images or cool buttons to the widget.

Name widget specs

The widget is programmed in JavaScript. It is minified to minimize the load time for your users.

The name widget  works crossbrowser. It is tested in Firefox, Internet Explorer 7+8, Opera and Chrome.

It follows the XHTML standarad set by the w3.org and validate as XHTML 1.1.

Do you want another name widget?

Do you want a business, superhero or maybe a fantasy name widget on your site, blog or  favorite forum?

Please contact me and let’s see if we can work out something. I’m always interested in some serious text link cooperation.

For another working example check this band name generator widget.

Name generator script

In this tutorial I’ll show how to make a simple name generator. A sort of  “build your own name generator” to experiment with. You just need to add your own word lists and you’re up and running.  But you can expand and modify the  name generator code to your own likings and abilities.

The name generator tutorial is very simple and are aimed at absolute beginners in web programming.

But enough talk, here is some name generator code that makes superhero names:

function generator(){
  // Add your own words to the wordlist. Be carefull to obey the showed syntax
  var adjectives = ["Cool","Masked","Bloody","Lame"]
  var animals = ["Hamster","Moose","Lama","Duck"]

  // Random numbers are made
  var randomNumber1 = parseInt(Math.random() * adjectives.length);
  var randomNumber2 = parseInt(Math.random() * animals.length);
  var name = adjectives[randomNumber1] + " " + animals[randomNumber2];

  alert(name); //Delete this when the below works            

  //If there's already a name it is removed  
  if(document.getElementById("result")){
    document.getElementById("placeholder").removeChild(document.getElementById("result"));
  }
  // A div element is created to show the generated name.
  //The Name is added as a textnode. Textnode is added to the placeholder.
  var element = document.createElement("div");
  element.setAttribute("id", "result");
  element.appendChild(document.createTextNode(name));
  document.getElementById("placeholder").appendChild(element);
}

The script is a simplified version of the one I use to make superhero names with my superhero generator.

The name generator piece by piece

The arrays

The most important part of  the name generator is the word lists. The more words in the list the more variety in the output. So the first part to do is to create a couple of arrays holding all our cool words:

var adjectives = ["cool","masked","bloody","lame"];
var animals = ["hamster","moose","lama","duck"]

To retrieve data  from the list we call the name of array with the count of the word as a parameter in a square bracket.  Be aware that counting in programming almost always starts at zero and not at 1.

So adjectives[0] is cool and  animals[1] gives moose

Randomness

We of course want random names, so we need to replace the hard coded numbers with random numbers. In our case numbers between 0 and 3 because we have 4 words in our lists. Instead of counting the words ourself, we do that we let the JavaScript length function do the counting. Then we multiply it with a random floating-point number between 0 and 0.9999999999999. Finally we use the parseInt funktion to make the floating-point number into a integer.

All sounds a bit complicated but code wise  it’s  quite easy.

randomNumber1 = parseInt(Math.random() * adjectives.length);
randomNumber2 = parseInt(Math.random() * animals.length);

The output

The most simple way to output the name is using the alert function. I use it only to check the generated name cause,  the alert box is  very annoying. So just delete the line, when the code below is up an running.

We will use 7 extra lines to integrate the result into the web page in a more natural way.

But before we begin you need to make an empty div tag in your HTML:

<div id=”placeholder”></div>

And here are the 7 lines that write the result in the page..

if(document.getElementById("result")){
  document.getElementById("placeholder").removeChild(document.getElementById("result"));
}

element = document.createElement("div");
element.setAttribute("id", "result");
element.appendChild(document.createTextNode(name));
document.getElementById("placeholder").appendChild(element);

In short it works like this:

1. If there’s already a result it is removed
2. Then a new div element to hold the result  is created
3. The name is added as a text node
4. Finally the element is appended to a placeholder in the HTML.

When this part works, you can delete the alert(name) from the script.

Putting it all together

The generator function can either be included in the head of the HTML document or you can place it in a external JavaScript file.

Now you can call the function from your HTML page.  I always do it 2 places. First in the body tag with an onload event. The generator function then also runs when the page is loaded.

<body onload=”generator()”>

And then I also call the JavaScript function on a button:

<input type=”button” onclick=”generator()” />
