I really need help on The Hunt Begins.

```
# Senick is trying to find the elusive Burleous Majoris!
# But he doesn't know how big a Burleous Majoris would be...
# Find the average size of this burl population to use as a baseline!
# This function returns average size of all the burls in an array.
def averageSize(burls):
sum = sumSize(burls)
# Remember the average is the sum of the parts divided by the amount!
return sum / burls.length
# This function should return the sum of all the burls sizes.
def sumSize(burls):
# Implement the sum function using the burls 'size':
s = burls.sum
return s
while True:
# Find the average size of the burls by calling the 'averageSize' function.
q = averageSize(burls)
# Say the average size of the seen burls!
hero.say(q)
```

It tells me burls is undefined

burls is obviously undefined, but how do I make the hero only look at burls?

Are you trying to find a list of all the burls?

If so,

```
burls = hero.findByType("burl")
```

Thank you! Now it does not give me any errors, but the hero does the functions before the burls come out, and therefore says â€ś0â€ť to Senick.

Here is my updated code:

```
# Senick is trying to find the elusive Burleous Majoris!
# But he doesn't know how big a Burleous Majoris would be...
# Find the average size of this burl population to use as a baseline!
# This function returns average size of all the burls in an array.
def averageSize(burls):
sum = sumSize(burls)
# Remember the average is the sum of the parts divided by the amount!
return sum / burls.length
# This function should return the sum of all the burls sizes.
def sumSize(burls):
# Implement the sum function using the burls 'size':
sum = sum(burls.size)
return sum
while True:
# Find the average size of the burls by calling the 'averageSize' function.
burls = hero.findByType("burl")
q = averageSize(burls)
# Say the average size of the seen burls!
hero.say(q)
```

@_TD_RodYT, I cannot find a way to make my hero say the average size *after* the burls come by.

Do you know a way? And if so, could you tell me what it is?

The instructions for this level are not really clear so Iâ€™ll make it more clear. When we pass `burls`

, we are passing a list of all the burls on the screen. You do not have to worry about your hero starting too early because you put the code inside a while loop.

Now, inside the sumSize function, you want to loop the code in a for loop.

- Define â€śsumâ€ť in sumSize. You can set it to 0. (Outside of the loop)
- Inside the for loop you want to keep on adding the burlâ€™s size to sum:

```
for burl in burls
sum = sum + burl.size;
```

Now that you have to total size of all the burls combined, you will divide it by burlsâ€™ length in averageSize to find the average weight. I usually donâ€™t give away free code like this but the goal of the level was unclearly stated in the Hints.

You want to make sure that there are burls (that the variable burls is not empty) before calling your averageSize function. You will have done this check MANY times before now - think back to basic levels on attacking.

This should not be a problem since there is a constant stream of burls in this level but @reesylou is correct.

Righhhhhhhhhhht. Thanks for refreshing my memory, @reesylou and @_TD_RodYT

This does not work for *all* the burls, because I donâ€™t know what to compare `burls.length`

to.

```
# Senick is trying to find the elusive Burleous Majoris!
# But he doesn't know how big a Burleous Majoris would be...
# Find the average size of this burl population to use as a baseline!
# This function returns average size of all the burls in an array.
def averageSize(burls):
sum = sumSize(burls)
# Remember the average is the sum of the parts divided by the amount!
return sum / burls.length
# This function should return the sum of all the burls sizes.
def sumSize(burls):
# Implement the sum function using the burls 'size':
if burls.length > 15:
sum = sum(burls.size)
return sum
while True:
# Find the average size of the burls by calling the 'averageSize' function.
burls = hero.findByType("burl")
q = averageSize(burls)
# Say the average size of the seen burls!
hero.say(q)
```

Make sure you read my last post.

In sumSize, you will need to create a for loop to find the total of every burlâ€™s size **combined**.

```
sum = 0
for burl in burls:
sum = sum + burl.size
```

Then, in averageSize, the function will divide the total size by the amount of burls. (to find the average size)

(I donâ€™t give out free code, but this level is a little confusing. I will delete this post when the devs change the Hints.)

Thank you! I agree, the hints did not make sense.

That worked! Thanks for the help, @reesylou and @_TD_RodYT!

def averageSize(burls):

sum = sumSize(burls)

return sum / len(burls)

def sumSize(burls):

```
sum = 0
for i in range(len(burls)):
burl = burls[i]
sum += burl.size
return sum
```

While True:

burls = hero.findEnemies()

avgSize = averageSize(burls)

hero.say(avgSize)

Can someone help out and tell me why this doesnâ€™t work?

thanks
