Returns a list with `n` elements removed from the right.
|
|
|
|
- Use slice notation to remove the specified number of elements from the right.
|
|
- Omit the last argument, `n`, to use a default value of `1`.
|
|
|
|
```py
|
|
def drop_right(a, n = 1):
|
|
return a[:-n]
|
|
```
|
|
|
|
```py
|
|
drop_right([1, 2, 3]) # [1, 2]
|
|
drop_right([1, 2, 3], 2) # [1]
|
|
drop_right([1, 2, 3], 42) # []
|
|
```
