Question

It seems like this is a common problem, but I can’t seem to find a solution.

I have a Python3 script containing two dictionaries sqldict and hitsdict. This code outputs dictionary values, if sqldict[value][0] == hitsdict[thing][1].

for value in sqldict:
        for thing in hitsdict:
            if sqldict[value][0] == hitsdict[thing][1]:
                print(hitsdict[thing][1],sqldict[value][5])

I would also like to get the keys that are associated with the values that match the sqldict[value][0] == hitsdict[thing][1] comparison, but I can’t seem to figure out how to get the associated keys? I was trying to do something like this:

for key, value in sqldict.items():
        for thing in hitsdict:
            if sqldict[value][0] == hitsdict[thing][1]:
                            print(key,hitsdict[thing][1],sqldict[value][5])

Can anyone explain what my problem is and how I can get the keys from values that pass my, if sqldict[value][0] == hitsdict[thing][1] comparison? Thank you!

EDIT:
One idea I had is to add the key as an addition value. Is there another more pythonic way?

Answer 1

You are finding values by looping through the items in the dictionary. That’s the wrong way. The whole purpose of the dictionary is to use the keys to look things up.

In short, your datastructure is completely messed up. Since we don’t know how it looks, we can’t tell you how it should look, but on the other hand, you have the word “sql” in one of the values.

May I suggest you use SQL queries to do whatever you do instead?
