again, your interpreter is too simple.
the solution “total = total + prices[food] * stock[food]” is the same as
total += prices[ x ] * stock[ x ] <-- i have to place a space before and after the “x” otherwise it becomes a check mark!
but the interpreter rejects it with an error!
Why does this work:
total = total + prices[fruit] * stock[fruit]
print total
#the sum of prices multiplied by the stock and returns 117.0
but this does not work and returns 0
total2 = prices[fruit] * stock[fruit]
Print total + total2
#new variable total2 should equal 117.0
#new variable total2 + total should equal 117.0

Why doesn’t my code work?
Your code doesn’t work because food is not a key. You should have switch the ‘food’ with key because its the key of the price and stock.
then after that you print the variable
