what would be the code that follows these rules?

Create a list with 10 numbers in it. Then call the function and pass your list to the function as a parameter.

Here is an example code that follows the given rules:

```
def my_function(numbers):
# perform desired operations with the list
# for example, print each number in the list
for number in numbers:
print(number)

# create a list with 10 numbers
my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# call the function and pass the list as a parameter
my_function(my_list)
```

In this code, we first define a function called `my_function` which takes a parameter `numbers`. This function can perform any desired operations with the list passed as a parameter.

Then, we create a list called `my_list` with 10 numbers.

Finally, we call the `my_function` and pass `my_list` as a parameter. This passes the list to the function for further processing. In this example, we simply print each number in the list.
