How to yield key and value in a dictionary if conditional is met

Here is my current code

guests = {'Jane': 35, 'Kyle': 20, 'Justin': 43, 'Ayla': 22}

age_check = (key, value for key, value in guests.items() if value >= 21)
for guest in age_check:
  print(guest)

I am curious how I would get the output of every key and value where the value is over than or equal to 21 using a generator expression.

I have tried the code that is shown above which returns a SyntaxError. I have also tried returning both the key and value but only iterating through the values which also returned a SyntaxError. I have also tried a few miniscule changes but am currently stumped. I am assuming both the value and the key have to be mentioned after the if but am unsure how or where.

Any help would be much appreciated. Thank you in advance.

Solution

From Displays for lists, sets and dictionaries: The comprehension consists of a single expression followed by at least one for clause. In your case, the expression key, value is ambiguous in this context (is that a tuple being generated or is the second value in the tuple a generator) so must be encased in parentheses.

age_check = ((key, value) for key, value in guests.items() if value >= 21)
