Hello all mentors online,

I'm quite confused about "len(numbers)" on the forth line

May anyone explain more to me how this len() could count the number of scores I put in rather than the decimal of a number?

I remember for a string:

len() is counting it's characters, right?

then for a number like 2533

len("2533") = 4, right?

how could len(numbers) count the amount of scores in the dictionary?

thank you all

```
def average(numbers):
total = sum(numbers)
total = float(total)
division = total/len(numbers)
return division
```
