Can I set a value based on a condition within a filter?

There are a bunch of variations for this but I am specifically looking for doing these two:

Within here I want to basically say:
If Variable X = 'string1' set value to True

And here:

If Variable Y = 'string2' set value to Variable Y

Are these possible or do I have to create a conditional line in the function list for each?
