Returns a list with `n` elements removed from the end.
|
|
|
|
- Use slice notation to create a slice of the list with `n` elements taken from the end.
|
|
|
|
```py
|
|
def take_right(itr, n = 1):
|
|
return itr[-n:]
|
|
```
|
|
|
|
```py
|
|
take_right([1, 2, 3], 2) # [2, 3]
|
|
take_right([1, 2, 3]) # [3]
|
|
```
