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`):
- There are 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.
