Converts a list of dictionaries into a list of values corresponding to the specified `key`.
|
|
|
|
- Use a list comprehension and `dict.get()` to get the value of `key` for each dictionary in `lst`.
|
|
|
|
```py
|
|
def pluck(lst, key):
|
|
return [x.get(key) for x in lst]
|
|
```
|
|
|
|
```py
|
|
simpsons = [
|
|
{ 'name': 'lisa', 'age': 8 },
|
|
{ 'name': 'homer', 'age': 36 },
|
|
{ 'name': 'marge', 'age': 34 },
|
|
{ 'name': 'bart', 'age': 10 }
|
|
]
|
|
pluck(simpsons, 'age') # [8, 36, 34, 10]
|
|
```
