How do you do it? I have this:

prices = {
"banana" : 4,
"apple" : 2,
"orange" : 1.5,
"pear" : 3,
}
stock = {
"banana" : 6,
"apple" : 0,
"orange" : 32,
"pear" : 15,
}

for key in prices:
print key
print "price: %s" % prices[key]
print "stock: %s" % stock[key]

total = 0
for x in prices:
total = prices[x] * stock[x]
print total

Does it also say in what way it isn't correct?
Things aren't just "wrong", there is some difference between the current state and what's considered correct. This difference says a great deal about what needs changing. So what's the difference?

Hi in the `instruction` they aske you to `loop throught` price and then made that operation
`prices[x] * stock[x]` and then `add it to total` so it should be like that

``````total = 0
for x in prices:
n = prices[x] * stock[x]
total += n
print total``````

I `stored` the a operation `inside n` and then `added it to total`

Thank-you for replies, I have got it now

#5

im sorry, i dont understand the `total += n` syntaxis, could you please explain it? thanks

HI you can do it like that

``````totale = totale + n
totale = totale + b``````

Its the same as..

``````totale += n
totale += b``````
