Please please please, someone help me, i'm desperate for help


First off, I want to thank you for opening my topic, and recognizing my need for help
What is wrong with my code here, for this lesson:

def compute_bill(food):
total = 0
for item in food:
total = total + food[item]
return total


We should be accumulating prices...

        total += prices[item]


Thank you Thank You Thank you, of all people in codeacademy, u are the only one who helped me, thank you,im eternally in debt for your kindness
