Unknown code formatting

Hi, I am trying to solve the exercise " Try/Except to Get a Key", but somehow my answer and the solution are no accepted in the first step. What am I not seeing?

caffeine_level = {“espresso”: 64, “chai”: 40, “decaf”: 0, “drip”: 120}

try:
print(caffeine_level[“matcha”])
except KeyError:
print(“Unknown Caffeine Level”)
