How do you check to see if the user entered more than one character? Complete the code. letter = input("Enter a letter: ") if _____ > 1: print("\nPlease guess a single letter.\n")

Use Python’s built-in len() function to find how many characters are in the string. So the condition is `len(letter) > 1`, which prints the warning when the user enters more than one character. The correct choice is `len(letter)`.
