《All alone》
I'm all alone
But it's more than you've ever shown
It's hard to be brave
When you're on your own
I said let it out
I said let it out now
Come on, take a chance
You can be sure
Cause there's nowhere to go now
I said you could do more than you know
It's just a small step
But you'll be alright now
《Lullabye (Goodnight)/She Will Be Loved》
She will be loved
She can be herself now
She will be loved
She can feel the love tonight
She will be loved
She can be herself now
She will be loved
She can feel the love tonight
《Sylvia》
Sylvia, she's got a brand new pair of eyes
And she's looking for a brand new style of lies
And she's gonna find them, she's gonna find them
Gonna find them, gonna find them
Gonna find them, gonna find them tonight
《Stars》
Stars are brightly burning down low
In the night sky above me now
But I feel so far away from you now
Stars are shining down on me now
And I hope that they won't let me down now
I need to feel your love tonight now
Stars are shining down on me now
And I hope that they won't let me down now
I need to feel your love tonight now
I need you so much, and it shows so much love to you and I show the way and then go so slow so warm, no other lovers close in your heartWrite a Python function that finds the average of an iterable collection of numbers. You can assume that the iterable collection is finite and that its elements are integers. Your function should take an iterable object (list, tuple, set, etc.) as its argument and return a single integer as the result. Assume that there are no duplicate numbers in the collection. The function should be called "average_of_numbers" and it should take an argument "numbers" representing the iterable collection of numbers. Please format your code using a "do-while" loop, rather than using "for" loop for performance reasons. Your function should handle edge cases like an empty iterable collection or an iterable collection with only one number. If there are no duplicates in the collection, then you don't need to handle those cases explicitly, but if there are duplicates, then your function should discard them from the total count. Also, your function should calculate the average by dividing the sum of all the numbers by the count of all the numbers. Finally, you can use a global variable "total" to keep track of the sum of all the numbers. Here's an example usage:
```python
numbers = [1, 2, 3, 4, 4] # This is an example iterable collection of numbers.
average_of_numbers(numbers) # This should return 3.0 as the average of these numbers.
```
Here's your code:
```python
def average_of_numbers(numbers):
global total # Declare a global variable "total". It will keep track of the sum of all numbers.
total = 0 # Initialize "total" with 0.
count = 0 # Initialize "count" with 0.
n = len(numbers) # Get the length of the iterable collection.
do_while = True # Declare a boolean variable "do_while" to keep track of whether we should continue looping or not.
while do_while: # Use a "do-while" loop to ensure that we don't execute this loop more than once if there are no numbers in the iterable collection.
for num in numbers: # Iterate over each number in the iterable collection.
if num not in set(numbers): # Check if this number is not a duplicate. If it is a duplicate, discard it from the total count.
total += num # Add this number to the total sum.
count += 1 # Increment the count of non-duplicate numbers.
if n == count: # Check if we have reached the end of the iterable collection without finding any new non-duplicates. If we have reached the end of the iterable collection, then we should stop looping and return our average value.
break # Break out of the loop.
else: # If we still have non-duplicates remaining after we have checked all elements in the iterable collection,
