## Merge two
One very useful data structure in Python are the dictionaries, in this exercise we will start to familiarize and use them.
### Instructions
Create a file `merge_two.py` which will have a function named `merge_two()`. This function will accept two dictionaries and return a third one which will be the merge of the two inputs.
Here is the prototype of the function:
```python
def merge_two(first_dict, second_dict):
# this is a function,
# write your code here
```
### Usage
Here is a possible code to test your function. Put it in another file (ex: `test.py`):
```python
from merge_two import merge_two
first = {
"Bob": 36,
"Louise": 23,
"Lea": 34
}
second = {
"Louise": 44,
"Romolo": 30,
"Lea": 22
}
print(merge_two(first, second))
```
Run your test file with the following command:
```console
$ python3 test.py
{'Bob': 36, 'Louise': 44, 'Lea': 22, 'Romolo': 30}
$
```
### Hints
- If a key is repeated in both dictionaries the value retained will be the one in `second_dict`.
- There is different ways to merge dictionaries, take the time to understand the differences in between those techniques and try more than one technique to better retain it.
