按降序排列文本文件中的单词

# 读取文本文件
with open('input.txt', 'r') as file:
    text = file.read()

# 分割文本并清洗单词
words = text.split()
cleaned_words = [word.strip('.,?!:;') for word in words]
cleaned_words = [word.lower() for word in cleaned_words]

# 统计单词频率
word_freq = {}
for word in cleaned_words:
    if word in word_freq:
        word_freq[word] += 1
    else:
        word_freq[word] = 1

# 排序单词
sorted_words = sorted(word_freq.items(), key=lambda x: x[1], reverse=True)

# 输出结果
with open('output.txt', 'w') as file:
    for word, freq in sorted_words:
        file.write(f"{word}: {freq}\n")
