Returns a random element from a list.
|
|
|
|
- Use `random.randint()` to generate a random number that corresponds to an index in the list, return the element at that index.
|
|
- [`random.sample()`](https://docs.python.org/3/library/random.html#random.sample) provides similar functionality to this snippet.
|
|
|
|
```py
|
|
from random import randint
|
|
|
|
def sample(lst):
|
|
return lst[randint(0, len(lst) - 1)]
|
|
```
|
|
|
|
```py
|
|
sample([3, 7, 9, 11]) # 9
|
|
```
