Tutorial: How to Make Generator Number Random in Python

Posted on

In this tutorial, we will guide you on how to create a generator number randomizer in Python. This skill is essential for any Python programmer who wants to generate random numbers efficiently. We will walk you through the process step by step, providing clear explanations and code examples.

Whether you’re a seasoned programmer or just starting, this tutorial will be beneficial in expanding your knowledge of random number generation in Python. Let’s dive in!

Understanding Random Number Generation in Python

Before we dive into creating a generator number randomizer in Python, it’s important to have a basic understanding of random number generation in Python.

The Concept of Random Numbers

Random numbers are numbers that are generated in a way that cannot be predicted beforehand. In programming, random numbers are often used for games, simulations, and scientific research.

Using Python’s Built-In Random Module

Python has a built-in module called random that can be used to generate random numbers. The random module contains functions for generating random integers, floats, and sequences.

The Advantages of the Numpy Library

The numpy library is a powerful Python library that provides many functions for working with arrays. It also includes a suite of functions for generating random numbers. The numpy library has advantages over the built-in random module, namely the ability to generate random numbers from any distribution and with a higher degree of control over the generated values.

Creating a Generator Number Randomizer in Python

Now that we have a good understanding of random number generation in Python, it’s time to create our own generator number randomizer. To do this, we will define a generator function that will generate random numbers based on certain criteria.

Step 1: Defining the Generator Function

The first step is defining the generator function. We will use the yield keyword to generate a new random number each time the function is called. Here’s an example:

import random

def generator_function():
    while True:
        yield random.randint(1, 100)

In this example, the generator_function generates a random integer between 1 and 100. The yield keyword allows the function to retain its state and generate a new random number each time it is called.

Step 2: Specifying Criteria for Random Number Generation

We can specify criteria for generating random numbers in the generator function. For example, we may want to generate only even numbers, or numbers that are divisible by 3. Here’s an example of a generator function that generates even numbers:

def even_generator():
    while True:
        num = random.randint(1, 100)
        if num % 2 == 0:
            yield num

In this example, the even_generator generates random numbers between 1 and 100, but only yields the number if it is even.

Step 3: Implementing the Generator Function in Code

Now that we have defined the generator function and specified the criteria for random number generation, we can implement it in our code. Here’s an example:

import random

def even_generator():
    while True:
        num = random.randint(1, 100)
        if num % 2 == 0:
            yield num

for number in even_generator():

In this example, the even_generator is called within a for loop, which generates and prints a new even number with each iteration.

By following these steps, we can create a generator number randomizer in Python that meets our specific needs.

Random Number Generator Apps Using GUI

import random
import tkinter as tk
from tkinter import Label, Entry, Button

def generate_random_number():
    min_value = int(min_entry.get())
    max_value = int(max_entry.get())
    random_number = random.randint(min_value, max_value)
    result_label.config(text=f"Random Number: {random_number}")

app = tk.Tk()
app.title("Random Number Generator")

min_label = Label(app, text="Min Value:")

min_entry = Entry(app)

max_label = Label(app, text="Max Value:")

max_entry = Entry(app)

generate_button = Button(app, text="Generate Random Number", command=generate_random_number)

result_label = Label(app, text="")


Advanced Techniques for Random Number Generation in Python

As we dive deeper into random number generation in Python, we can explore more advanced techniques to generate numbers for specific applications. Let’s take a look at some of these techniques:

Generating Random Numbers from a Specific Distribution

While Python’s built-in random module is sufficient for most simple applications, the numpy library provides additional functionality for generating random numbers from specific distributions. For example, you can generate random numbers from a normal distribution with numpy.random.normal or from a uniform distribution with numpy.random.uniform.

These distributions are widely used in scientific and financial applications, and understanding how to generate them can greatly enhance your programming skills.

Creating Random Strings

Generating random strings is a common task in programming. Python provides several methods to generate random strings, such as using the random.choice function to randomly select characters from a given set of characters. You can also use the string module to generate strings with specific properties, such as lowercase letters or digits.

Random strings are used in various applications, such as generating temporary passwords or session IDs.

Sampling Elements from a List

Python provides a built-in random.sample function for randomly selecting a specified number of elements from a list without duplicates. This function can be useful for applications such as selecting random items from a list of products or selecting random participants for a survey.

Overall, mastering these advanced techniques for random number generation in Python can enhance your ability to write efficient and effective code for a variety of applications.


Generating random numbers is a crucial skill for any Python programmer, and we hope this tutorial has provided you with valuable insights on how to master it. Now that you have learned how to create a generator number randomizer, we encourage you to experiment with different techniques to expand your coding expertise.

Keep Practicing

Remember, practice makes perfect! Don’t be afraid to try out different techniques and test new ideas. The more you practice generating random numbers, the more confident you will become in your coding abilities.
