## Steps:

1. Generate the list of odd numbers between 1 to 10 using list comprehension
2. Develop a test function using a generator of numbers to test the `Calculator` class
3. Create a division by zero check decorator: `@check_dbz`


## Example of a generator function:
```python
def test_number_generator(start, stop):
    n = start
    while n < stop:
        yield n+1, n
        n += 1
```
