# How to Generate Random Integers in Range in Python

Python is a popular programming language when working with math and data because of how easy it is to work with numbers.

A popular operation in Python is to generate random numbers in a specific range so that you can use it in your code.

In this post, we'll learn how to generate random numbers in a specific range in Python.

## Using random.randint()

A simple way to generate random numbers in a specific range is to use the `randint()`

function.

This function comes from the `random`

module and you can use it by just importing it.

Let's look at how to generate a random number between 0 and 10 in Python:

` ````
import random
number = random.randint(0, 10)
print(number)
```

` ``5`

Keep in mind that this will include the number `0`

but exclude the number `10`

.

Now, if you want to generate a list of these numbers, you can use the `range()`

function:

` ````
import random
numbers = [random.randint(0, 10) for p in range(0, 10)]
print(numbers)
```

` ``[1, 8, 4, 0, 5, 9, 2, 3, 6, 8]`

Here is the general syntax:

` ````
import random
range_start = 0
range_end = 10
gen_count = 10
numbers = [random.randint(range_start, range_end) for p in range(0, gen_count)]
print(numbers)
```

## Using random.randrange()

Another function that comes with the `random`

module is `randrange()`

.

This function also requires a start and end range, however, it also allows you to specify a step size.

The `step`

parameter is optional, but if you don't specify it, it will default to `1`

.

This parameter controls the step size of the range, so if you want to generate a list of numbers between 0 and 10, but only in steps of 2, you can use the following syntax:

` ````
import random
numbers = [random.randrange(0, 10, 2) for p in range(0, 10)]
print(numbers)
```

` ``[4, 2, 6, 2, 4, 8, 6, 4, 2, 2]`

## Using random.sample()

When you want to ensure that you have a random list of unique numbers, you can use the `sample()`

function.

This function will generate a random list of integers for you while ensuring they are all unique.

Let's see how it works:

` ````
import random
numbers = random.sample(range(0, 10), 10)
print(numbers)
```

` ``[4, 3, 8, 1, 7, 2, 9, 6, 0, 5]`

## Conclusion

In this post, we learned how to generate random numbers in a specific range in Python.

Python has several built-in functions that you can use to generate the random numbers that you need. Simply pick the one that is right for your use-case.
