Python check the whole loop before going to the else statement

How do I run through the whole loop and then after go to else statement, if the if condition is false?

The output is:

No

No

Yes

But I only want it to jump to the else statement if all of the values does not equal!

test_1 = (255, 200, 100)
test_2 = (200, 200, 100)
test_3 = (500, 50, 200)

dict = {"test_1":test_1,
        "test_2":test_2,
        "test_3":test_3}


for item in dict:
   if dict[item] == (500, 50, 200):
        print('Yes')
   else:
        print('No')

So basicly the output should say, because one of the values was true.

Yes
