I don’t understand the hunt begins, its something I don’t understand, could you explain

I does not matter, but here is my code

```
def averageSize(burls):
sum = sumSize(burls)
# Remember the average is the sum of the parts divided by the amount!
return sum / len(burls)
# This function should return the sum of all the burls sizes.
def sumSize(burls):
# Implement the sum function using the burls 'size':
ProbablyNeedAvariableOrSomething = 0
pass
while True:
# Find the average size of the burls by calling the 'averageSize' function.
averageSize("burls")
# Say the average size of the seen burls!
hero.say(averageSize("burls"))
```
