# How to create a list of random integers in python ?

Examples of how to create a list of random integers in python:

### Using the function randint

The python function randint can be used to generate a random integer in a chosen interval [a,b]:

````>>> import random`
`>>> random.randint(0,10)`
`7`
`>>> random.randint(0,10)`
`0`
```

A list of random numbers can be then created using python list comprehension approach:

````>>> l = [random.randint(0,10) for i in range(5)]`
`>>> l`
`[4, 9, 8, 4, 5]`
```

### Using the function randrange

Another solution is to use randrange function (except that can specify a step if you need):

````>>> l = [random.randrange(0,10) for i in range(5)]`
`>>> l`
`[1, 7, 4, 3, 1]`
`>>> l = [random.randrange(0,10,2) for i in range(5)]`
`>>> l`
`[2, 4, 4, 6, 0]`
```

### Using the function sample

To create a list of random numbers with no repetition, a solution is to use random.sample function

````>>> l = random.sample(range(1,100), 10)`
`>>> l`
`[89, 56, 87, 51, 46, 25, 52, 44, 10, 32]`
```
