I've made an anagram function in python, I cannot figure out how to get the output to look like this: “Key”: word1, word2, word3 etc

Question

with open(\'words.txt\', \'r\') as read:
    line = read.readlines()

key_list = []

def make_anagram_dict(line):
    word_list = {}

    for word in line:
        word
