The random module in Python is commonly used to generate pseudo-random numbers. In this blog post, we will explore the most widely used random functions in Python and how you can apply them in your projects. Whether you are a beginner or looking to refresh your knowledge, this guide will help you understand how these functions work and when to use them.

1. random()
The random() function generates a pseudo-random float number. It returns a floating-point number in the range of [0, 1), meaning it is greater than or equal to 0 but less than 1.It takes no positional argument.
Syntax-random.random()
2. randrang()
The randrange() function selects an integer from a specified range. It can take one, two, or three arguments: start, stop, and step. The value returned will be in the range [start, stop), meaning it includes start but excludes stop.
Syntax –random.randrange(start, stop [, step])
3. randint()
The randint() function generates a random integer within a specified range, inclusive of both the start and stop values. It takes 2 positional arguments and used when we know the start and stop values.
Syntax-random.randint(start, stop)
4. uniform()
The uniform() function generates a random floating-point number within the specified range. It takes two parameters: start and stop. The generated number is greater than or equal to start and less than or equal to stop.
Syntax-random.uniform(start, stop)
5. choice()
The choice() function, introduced in Python 3.6, randomly selects an item from a sequence (e.g., a list, tuple, or string). This function can be used when you want to select an element from an iterable.
Syntax-random.choice(iterable element)
6. seed()
The seed() function initializes the random number generator with a fixed value. This ensures reproducibility, meaning you can generate the same sequence of random numbers every time you run the code. This is especially useful in testing and debugging scenarios.
Syntax- random.seed(number)
This concludes our overview of the most widely used random functions in Python. These functions allow you to generate random numbers and make your code more dynamic and flexible. For more Python concept, check out our Python programming blog.
