(I'm new to Python!)
Trying to figure out this homework question:
The function will takes a​s input​ two dictionaries, each mapping strings to integers. The function will r​eturn​ a dictionary that maps strings from the two input dictionaries to the sum of the integers in the two input dictionaries.

my idea was this:

```
def ​add(​dicA,dicB):
    dicA = {}
    dicB = {}
    newdictionary = dicA.update(dicB)

```

however, that brings back `None`.

In the professor's example:

```
print(add({'alice':10, 'Bob':3, 'Carlie':1}, {'alice':5, 'Bob':100, 'Carlie':1}))

```

the output is:

```
{'alice':15, 'Bob':103, 'Carlie':2}

```

My issue really is that I don't understand how to add up the values from each dictionaries. I know that the '+' is not supported with dictionaries. I'm not looking for anyone to do my homework for me, but any suggestions would be very much appreciated!
