在上面的代码中加入一个程序“每猜一次，根据提供的字符串(例如a _ _ le)与字典中所有可能的单词进行匹配，将这些可能的单词中出现的字母频率制成表格，然后猜测出现频率最高的尚未被猜测的字母。如果没有剩余的单词匹配，那么它将默认返回到整个字典的字符频率分布。“

好的，我理解了你的要求。下面是你想要的功能的代码实现：

import random
from collections import Counter

def guess_word(word_list):
    guessed_letters = set()
    word = random.choice(word_list)
    guessed_word = ['_'] * len(word)
    
    while True:
        print(' '.join(guessed_word))
        letter_freq = Counter(''.join(word_list) + ''.join(guessed_letters))
        sorted_freq = sorted(letter_freq.items(), key=lambda x: x[1], reverse=True)
        for letter, freq in sorted_freq:
            if letter not in guessed_letters:
                guessed_letters.add(letter)
                break
        else:
            print('No more letters to guess. The word is:', word)
            break
        
        guess = input('Guess a letter: ').lower()
        if guess in guessed_letters:
            print('You already guessed that letter. Try again.')
        elif guess in word:
            print('Good job! The letter is in the word.')
            for i in range(len(word)):
                if word[i] == guess:
                    guessed_word[i] = guess
            if '_' not in guessed_word:
                print('Congratulations! You guessed the word:', word)
                break
        else:
            print('Oops! The letter is not in the word.')
            
            new_word_list = []
            for w in word_list:
                if all(w[i] == guessed_word[i] or guessed_word[i]=='_' for i in range(len(w))) and guess not in w:
                    new_word_list.append(w)
            if not new_word_list:
                new_word_list = word_list
            word_list = new_word_list
            word = random.choice(word_list)
            
            if len(word_list) == 1:
                print('The word is:', word_list[0])
                break
                

word_list = ['apple', 'banana', 'cherry', 'orange', 'pear', 'peach', 'pineapple', 'strawberry']
guess_word(word_list)

这个程序会在每次猜测后，根据提供的字符串与剩余的单词进行匹配，将这些可能的单词中出现的字母频率制成表格，然后猜测出现频率最高的尚未被猜测的字母。如果没有剩余的单词匹配，那么它将默认返回到整个字典的字符频率分布。
