I did like that and i think the time complexity is O(n)
count = dict(zip(queries, [0] * len(queries)))
for stri in stringList:
if stri in count:
count[stri] += 1
return list(count.values())

I did mine like this and got and it passed the samples. Is the way i did it wrong?

a = []


        a.append(x)

    return a
