Confusing subject for a confusing problem (to a novice like me of course!)

Thx for the help in advance folks

I have (2) dictionaries:

prices = {

"banana": 4,

"apple": 2,

"orange": 1.5,

"pear": 3

}

stock = {

"banana": 6,

"apple": 0,

"orange": 32,

"pear": 15

}

Here's my instructions:

consider this as an inventory and calculate the sum (thats 4*6 = 24 bananas!)

Let me reword your problem a little, maybe it'll be a bit clearer.

You're trying to calculate the total value of all stock on hand, eg

for insurance purposes. That's not 24 bananas, that's $24 of bananas.

And the part you want now is to get the total value of your entire

stock. Great! You're very close to there...

HERES MY CODE:

for key in prices:

print prices[key]*stock[key]

ISSUE:

I need to find a way to add all of those together...any pointers?

.... you just need to accumulate a sum. Since this is almost certainly

homework, I won't give you the answer, but here are a few pointers:

* You'll need a single variable (I use the term sloppily, Python

doesn't actually have variables per se) which will collect the final

total.

* Inside your loop, you're currently printing out an int/float with

the value of the current item. Just add it onto your accumulator.

* Python will happily work with integers and floats together, so you

can just do what's obvious and it'll work.

See where that takes you. Have fun!
