# Python Lists and Dictionaries

#1

Oops, try again. Make sure to add 50 to the gold total!

the error messages may not express all my error, I mistake the dic and list, so I can not correctly answer.
who can kindly tell me Is there a correct and more simple way to solving it? thanks a lot!

``````inventory = {
'gold' : 500,
'pouch' : ['flint', 'twine', 'gemstone'], # Assigned a new list to 'pouch' key
}

# 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'
inventory['pouch'].sort()

inventory['pocket'] = ['seashell', 'strange berry','lint']

inventory['backpack'].sort()

inventory['backpack'].remove('dagger')

inventory['gold']=[500+50]``````

here..
`inventory['gold']=[500+50]` (why're you putting the value in a list? )

You have to increase value of `gold` key by 50

suppose..
x is an integer.

`x = 40`

I want to increase its value by 30, I'd do this..
`x = x + 30`

Keep in mind that there you have to use key `gold` that have corresponding value 500 now.
You need to increase it's value by 50.

#3

I know,I don't know how to increase the 50? I used to try..

`inventory['gold']=[550]`

How can I show the calculating process?

#4

Thanks a lot, I succeed.

`inventory['gold']+=50`

#5

How did you figure this out? I never would've guessed += to add the numbers based on everything learned.

Good job, by the way!

#6

I guess it likes:
`inventory['gold']=50+inventory['gold']`
