问如何同时显示从字典中获取的键和更新值？

EN

dangerous : ['hazardous', 'perilous', 'uncertain'] 
show : ['communicate', 'manifest', 'disclose']
slow : ['leisurely', 'unhurried']

word_dict = {'show': ['display', 'exhibit', 'convey', 'communicate', 'manifest', 'disclose'],
             'slow': ['unhurried', 'gradual', 'leisurely', 'late', 'behind', 'tedious', 'slack'],
             'dangerous': ['perilous', 'hazardous', 'uncertain']}

def main():
    edited_synonyms = remove_word(word_dict)
    key_order(edited_synonyms)

def remove_word(word_dict):
    dictionary = {}

    synonyms_list = word_dict.values()
    new_list = []
    for i in synonyms_list:
        new_list.extend(i)

    for word in new_list:
        letter_length = len(word)
        if letter_length <= 7:
            new_list.pop(new_list.index(word))

    value = new_list 
    keys_only = word_dict.keys()
    key = keys_only
    dictionary[key] = value
    return dictionary


def key_order(word_dict):
    word_list = list(word_dict.keys())
    word_list.sort()
    for letter in word_list:
        value = word_list[letter]
        print(letter, ": ", value)
