What are the different ways to generate a random number in python?

Python makes it very easy to generate random numbers in many different ways. In order to do this, you’ll learn about the random and numpy modules, including the randrange, randint, random, and seed functions. You’ll also learn about the uniform and normal functions in order to create more controlled random values.

What is the randint function?

The randint () function returns an integer value (of course, random!) between the starting and ending point entered in the function. This function is inclusive of both the endpoints entered. The function returns the number 5 as a random output.

What is the randbelow function?

The randbelow ()function is inclusive of both the limits entered in the function. The use of random test cases is immense in programming. The built-in functions of several programming languages make it easier for us- the programmers to execute millions of arbitrary test cases and develop an efficient and accurate program.

What is the range for the randint() method?

The random () method in random module generates a float number between 0 and 1. The randint () method generates a integer between a given range of numbers. We can use the above randint () method along with a for loop to generate a list of numbers.
