# How to Generate Random Integers in Python?

The most idiomatic way to create a random integer in Python is the `randint()` function of the `random` module. Its two arguments `start` and `end` define the range of the generated integers. The return value is a random integer in the interval `[start, end]` including both interval boundaries. For example, `randint(0, 9)` returns an integer in 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Let’s explore a couple of examples next.

## Generate a Random Integer Between 0 and 9

To create a random integer between 0 and 9, call `random.randint(0, 9)`.

```import random
num = random.randint(0, 9)```

The output can be any number between 0 (included) and 9 (included).

## Generate a Random Integer Between 1 and 10

To create a random integer between 1 and 10, call `random.randint(1, 10)`.

```import random
num = random.randint(1, 10)```

The output can be any number between 1 (included) and 10 (included).

## Generate a Random Integer Between 1 and 100

To create a random integer between 1 and 100, call `random.randint(1, 100)`.

```import random
num = random.randint(1, 100)```

The output can be any number between 1 (included) and 100 (included).

## Generate a Random Integer Between x and y

To create a random integer `num` between `x` and `y` so that `x <= num <= y` holds, call `random.randint(x, y)`.

```import random
x, y = 0, 10
num = random.randint(x, y)```

The output can be any number between `x` (included) and `y` (included).

## randrange()

An alternative way to create random integers within a certain range in Python is the `random.randrange()` function. This allows you more flexibility to define the range from which the random numbers should be drawn.

Here’s the usage overview with three different sets of arguments:

Here are three example runs in my Python shell:

```>>> import random
>>> random.randrange(3)
1
>>> random.randrange(2, 3)
2
>>> random.randrange(2, 10, 2)
2```
