Chunks a list into `n` smaller lists.
|
|
|
|
- Use `math.ceil()` and `len()` to get the size of each chunk.
|
|
- Use `list()` and `range()` to create a new list of size `n`.
|
|
- Use `map()` to map each element of the new list to a chunk the length of `size`.
|
|
- If the original list can't be split evenly, the final chunk will contain the remaining elements.
|
|
|
|
```py
|
|
from math import ceil
|
|
|
|
def chunk_into_n(lst, n):
|
|
size = ceil(len(lst) / n)
|
|
return list(
|
|
map(lambda x: lst[x * size:x * size + size],
|
|
list(range(n)))
|
|
)
|
|
```
|
|
|
|
```py
|
|
chunk_into_n([1, 2, 3, 4, 5, 6, 7], 4) # [[1, 2], [3, 4], [5, 6], [7]]
|
|
```
