How to Generate a Random Number in Python

In this article, we show how to generate a random number in Python.

To generate a random number in Python, we must import the random module.

Once we have this random module imported, we can generate random floats or integers in any interval that we want.

How to Generate Random Floats

To generate a random float number between 0 and 1, you can use the line, random.random(), in order to do so

import random random.random()

Using the line above will yield a number between 0 and 1.

If you want a random float between a certain range, then you would multiply random.random() by the range that you want.

For example, if you want to generate a random float between 0 and 10, then you would multiply random.random() by 10.

So, the code would be that which is shown below.

import random random.random() * 10

So, this code above will now generate a random float between 0 and 10.

If you want to generate a random float between 0 and 100, then you would multiply random.random() by 100.

How to Generate a Random Integer

To generate a random integer in Python, you would use the line random.randint() function. Inside of the parameter of the randint() function, you would put the range that you want returned.

For example, if you want to generate a random integer between 1 and 10, the statement would be, random.randint(1,10).

This is shown in the code below.

import random random.randint(1,10)

So, the code above will return a random integer between 1 and 10.

If you wanted to generate a random integer between 1 and 100, the code would be, random.randint(1,100).

And this is how random numbers can be generated in Python.
