Merges two or more dictionaries.
|
|
|
|
- Create a new `dict` and loop over `dicts`, using `dictionary.update()` to add the key-value pairs from each one to the result.
|
|
|
|
```py
|
|
def merge_dictionaries(*dicts):
|
|
res = dict()
|
|
for d in dicts:
|
|
res.update(d)
|
|
return res
|
|
```
|
|
|
|
```py
|
|
ages_one = {
|
|
'Peter': 10,
|
|
'Isabel': 11,
|
|
}
|
|
ages_two = {
|
|
'Anna': 9
|
|
}
|
|
merge_dictionaries(ages_one, ages_two)
|
|
# { 'Peter': 10, 'Isabel': 11, 'Anna': 9 }
|
|
```
