2 posts were split to a new topic: Am getting an error about the the “Orange key”


In writing the following code:

prices = {“banana”: 4,“apple”: 2,“orange”: 1.5,“pear”: 3}

stock = {“banana”: 6, “apple”: 0, “orange”: 32, “pear”: 15}

for food in prices:
print food
print “price: %s” % prices[food]
print “stock: %s” % stock[food]

How was I supposed to know that “apple” was categorized and can be called with the term “food”? There is no indication that this is how the info was stored.


I totally agree,
My code was like 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]
And it worked, yet it gave me the exercise as failed.


so this was what i used to get the “print EXACTLY the following format” format, but it marked it as fail


and when i hit solution, it gave a format of


which isn’t in the EMPHASIZED IN CAPS exact format as listed in the instructions. Should fix your instructions to reflect the answer or fix your answer to reflect the instructions
