Compare Django ValuesListQuerySet elements to List elements

I have two variables:

var1 ex: [6, 2, 4, 5] type: ValuesListQuerySet
var2 ex: ['4', '2'] type: List

I must compare the elements of these two variables , the result should be:

['4', '2']

My code:

idmatch = []
for r in var1:
    for k in var2:
        if k == r:
            print("here")
            idmatch.append(str(k))

The two elements are never the same , and the result is:

[]

How can i compare them?

Thank you

Your ValuesListQuerySet contains integers, but your list contains strings.

If you are not concerned about the order, the easiest solution is to convert both variables to sets.

# convert var1 to a set of strings
var1 = set(str(x) for x in var1)
# convert var2 to a set
var2 = set(var2)
idmatch = var1 & var2

The difference is not queryset vs list, but the content of those; one has integers, the other has strings.
