### keys_only
|
|
|
|
Function which accepts a dictionary of key value pairs and returns a new flat list of only the keys.
|
|
|
|
Uses the .keys() method of "dict" objects. dict.keys() returns a view object that displays a list of all the keys. Then, list(dict.keys()) returns a list that stores all the keys of a dict.
|
|
|
|
``` python
|
|
def keys_only(flat_dict):
|
|
return list(flat_dict.keys())
|
|
```
|
|
|
|
``` python
|
|
ages = {
|
|
"Peter": 10,
|
|
"Isabel": 11,
|
|
"Anna": 9,
|
|
}
|
|
keys_only(ages) # ['Peter', 'Isabel', 'Anna']
|
|
``` |
