# Finding Rotten Apples Explained
The state of apples is given in a list, where rotten apples are represented as '0', and fresh apples as '1'.
The function takes this list as input and returns the `positions (indices) of rotten apples` in a `list format`.
<br />
```python title="Sample Solution"
def solution(apples):
return [index for index, apple in enumerate(apples) if apple == 0]
-
Using
enumerate(apples), retrieve the index and value of each apple. -
Filter out rotten apples with
if apple == 0. -
Use list comprehension to return all indices of rotten apples.
Usage Example
Input and Output Example
