Inverts a dictionary with unique hashable values.
|
|
|
|
Use `dictionary.items()` in combination with a list comprehension to create a new dictionary with the values and keys inverted.
|
|
|
|
```py
|
|
def invert_dictionary(obj):
|
|
return { value: key for key, value in obj.items() }
|
|
```
|
|
|
|
```py
|
|
ages = {
|
|
"Peter": 10,
|
|
"Isabel": 11,
|
|
"Anna": 9,
|
|
}
|
|
invert_dictionary(ages) # { 10: "Peter", 11 "Isabel", 9: "Anna" }
|
|
```
