Write a function uniques (group1, group2) that returns the number of unique members in both group1 and group2. You're expected to solve this using sets. Note: the inputs group1 and group2 are always lists, but could be empty. For example: Test group1 = ["Tom", "Jerry", "Fiona", "Michael", "Bob"] 8 group2 = ["Terry", "Larry", "Fiona", "Bob", "Violet"] print (uniques (group1, group2)) group1 = [] group2 = ["Terry", "Larry", "Fiona", "Bob", "Violet"] print (uniques (group1, group2)) Result group1 = [1, 2, 3, 4, 5] group2 = [2, 3, 4, 5, 6] print (uniques (group1, group2)) 5 6

![### Function to Determine Number of Unique Members in Two Groups
#### Task Requirement
Write a function `uniques(group1, group2)` that returns **the number of unique members in both group1 and group2**.
#### Key Expectations
- Solve this using sets.
#### Input Specifications
- The inputs `group1` and `group2` are always lists but could be empty.
#### Example Usage
Here are example test cases and corresponding outputs:
##### Test Case 1
```python
group1 = ["Tom", "Jerry", "Fiona", "Michael", "Bob"]
group2 = ["Terry", "Larry", "Fiona", "Bob", "Violet"]
print(uniques(group1, group2))
```
**Result:**
```plaintext
8
```
**Explanation:**
The unique members across both lists are: Tom, Jerry, Fiona, Michael, Bob, Terry, Larry, Violet.
##### Test Case 2
```python
group1 = []
group2 = ["Terry", "Larry", "Fiona", "Bob", "Violet"]
print(uniques(group1, group2))
```
**Result:**
```plaintext
5
```
**Explanation:**
The unique members, in this case, are directly taken from group2 since group1 is empty: Terry, Larry, Fiona, Bob, Violet.
##### Test Case 3
```python
group1 = [1, 2, 3, 4, 5]
group2 = [2, 3, 4, 5, 6]
print(uniques(group1, group2))
```
**Result:**
```plaintext
6
```
**Explanation:**
The unique members across both lists are: 1, 2, 3, 4, 5, 6.
### Graph and Diagram Explanation
There are no graphs or diagrams in the provided example. The data is presented in a tabular format, displaying different test scenarios under the "Test" column and their respective results under the "Result" column. Each test scenario includes the elements in `group1` and `group2` as well as the function call to `uniques(group1, group2)`.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2b3c45ef-1cfd-4f2a-b84e-474203f12787%2F42bcdb25-e3a7-45bd-a496-6bc1aeb1848d%2Fmpy8eyr_processed.png&w=3840&q=75)
