I have a string and I created a JSON array which contains strings and values:

amount = 0

a = "asaf,almog,arnon,elbar"

values_li={'asaf':'1','almog':'6','elbar':'2'}

How can I create a loop that will search all items on values_li in a and for each item it will find it will do

amount = amount + value(the value that found from value_li in a)

I tried to do this but it doesn't work:

for k,v in values_li.items():

    if k in a:

        amount = amount + v

It's working.
I figure out my problem.
v is a string and I tried to do math with a string so I had to convert v to an int

amount = amount + int(v)

Now It's working :)

You should be careful using:

if k in a:

a is the string: "asaf,almog,arnon,elbar" not a list. This means that:

"bar" in a # == True
"as" in a # == True

..etc Which is probably not what you want.

You should consider splitting it into an array, then you'll only get complete matches. With that you can simply use:

a = "asaf,almog,arnon,elbar".split(',')

values_li={'asaf':'1','almog':'6','elbar':'2'}



amount = sum([int(values_li[k]) for k in a if k in values_li])

# 9

collections.Counter() is your friend:

from collections import Counter

a = "asaf,almog,arnon,elbar"

values_li = Counter({'asaf':1,'almog':6,'elbar':2})

values_li.update(a.split(','))

values_li

That will result in:

Counter({'almog': 7, 'elbar': 3, 'asaf': 2, 'arnon': 1})

And if you want the sum of all values in values_li, you can simply do:

sum(values_li.values())

Which will result in 13, for the key/value pairs in your example.
