14. It's Dangerous to Go Along! Take This: KeyError 'backpack"


I seem to be having an issue where I keep getting the error, line 16 KeyError: 'backpack' yet I have checked the spelling in all places and it matches up exactly. I have done my best to check the rest of my code cause you know there could always be something else causing it.

I have included all my code below

inventory = {
    'gold' : 500,
    'pouch' : ['flint', 'twine', 'gemstone'], # Assigned a new list to 'pouch' key
    'backpack' : ['xylophone','dagger', 'bedroll','bread loaf']

# Adding a key 'burlap bag' and assigning a list to it
inventory['burlap bag'] = ['apple', 'small ruby', 'three-toed sloth']

# Sorting the list found under the key 'pouch'

# Your code here
inventory = {"pocket": ["seashell", "strange berry", "lint"]}






inventory = {"pocket": ["seashell", "strange berry", "lint"]}
print inventory

you overwrote inventory, so your dictionary no longer contains a backpack

look at how you add burlap bag to dictionary, that might help you


The question was about line 16 and why .add(50) doesn't work. Thanks


overwriting your dictionary and then trying to increase something in a dictionary which is no longer there (because you overwrote), is the first problem.

yes, .add() is not valid, i know that, but i read the code from top to bottom, finding the first issue


I found from the other thread that this is working. It actually means the sum instead of appending a number to the list.
inventory["gold"] = inventory["gold"] + 50


You have the correct answer for line 16. The following is my code, and the only difference is that I used single quotes instead of double quotes around 'dagger':


Perhaps you were experiencing a temporary glitch. Try it again.

For line 17, it also worked for me to do:

inventory["gold"] = inventory["gold"] + 50
