Get A Random Number Between 0 0200 And 0 120 Float Numbers Duplicate

Random numbers play a crucial role in software engineering, whether you're developing a game, statistical model, or anything that requires unpredictability. In this guide, we will walk you through how to generate a random number between 0.0200 and 0.1200, specifically as a floating-point number, without duplicates.

To accomplish this task, we will leverage mathematical functions to manipulate the range and precision of the random numbers generated. Essentially, we want to create a function that can provide us with a unique random floating-point number between 0.0200 and 0.1200 each time it is called.

One way to achieve this is by utilizing a combination of the `random` module in Python and some basic arithmetic operations. You can follow these step-by-step instructions to implement the solution:

1. Import the `random` module at the beginning of your Python script or program:

import random

2. Define a function that generates the desired random floating-point number within the specified range:

def generate_random_number():
    return round(random.uniform(0.02, 0.12), 4)

3. Implement a mechanism to ensure that the generated random number is not a duplicate:

def generate_unique_random_number(existing_numbers):
    while True:
        random_number = generate_random_number()
        if random_number not in existing_numbers:
            existing_numbers.append(random_number)
            return random_number

4. As you call the `generate_unique_random_number` function, pass a list containing numbers that have already been generated to prevent duplicates:

existing_numbers = []
for _ in range(10):  # Generate 10 random numbers without duplicates
    unique_random_number = generate_unique_random_number(existing_numbers)
    print(unique_random_number)

By executing the above code, you will produce a series of unique random floating-point numbers within the specified range. The `round` function is used to limit the precision of the generated numbers to four decimal places, ensuring consistency in the output format each time.

Remember that the `random` module in Python utilizes pseudo-random number generators to produce seemingly random outcomes, but the sequence can be reproduced if the initial seed is known. However, for most practical purposes, this level of randomness is sufficient.

In conclusion, generating unique random floating-point numbers within a specific range is a common requirement in software development. By incorporating the techniques outlined in this article, you can easily implement a solution that meets this need efficiently and reliably. Don't hesitate to experiment with different ranges and precision levels to tailor the output to your specific requirements. Happy coding!
