Accessing items in lists within dictionary python

Question

I have a dictionary that has keys associated with lists.

mydict = {\'fruits\': [\'banana\', \'apple\', \'orange\'],
         \'vegetables\': [\'pepper\', \'carr         


        

Answer 1

You'll have to use a for, a simple if is not enough to check an unknown set of lists:

for key in mydict.keys():
    if item in mydict[key]:
        print key

An approach without an explicit for statement would be possible like this:

foundItems = (key for key, vals in mydict.items() if item in vals)

which returns all keys which are associated with item. But internally, there's still some kind of iteration going on.
