in line 10 were is the mistake?

The mistake in line 10 is missing an indentation. The code should be indented to indicate that it is part of the if statement block. Here is the corrected code:

if choice == "1":
print("You look around the room and find a key on the floor!")
has_key = True
elif choice == "2":
if has_key:
print("You already searched the dresser and found nothing.")
else:
print("You search the dresser and find a key!")
has_key = True
else:
print("Invalid choice. Please enter 1 or 2.")
