Help me in solving PYHANG05 problem

My issue

what is “have you forgot to greet?”

My code

import time
import random

def choose_word():
    words = ['codechef', 'programming', 'learning', 'practice', 'contests', 'rating']
    return random.choice(words)


def wordDisplay(word, guesses):
    display_word = ''
    # Solution as follows
    for char in word:
        if char in guesses:
            display_word += char + ' '
        else:
            display_word += '_ '
    return display_word


if __name__ == '__main__':
    word = choose_word()
    #print("Word selected for this round is '" + word + "'")    -- You can uncomment this line to test your code

    guesses = ''
    while True:    
        print(wordDisplay(word, guesses))
        guess = input("\nguess a character: ").lower()
        guesses += guess
