分别统计word在目录中所有文件中的出现次数

import os

def count_word_in_files(directory, word):
    count = 0
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            with open(file_path, 'r') as f:
                content = f.read()
                words = content.split()  # 拆分为单词列表
                count += words.count(word)  # 统计出现次数
    return count

# 使用示例
directory = '/path/to/directory'  # 替换为目标目录的路径
word = 'word'  # 替换为目标单词
result = count_word_in_files(directory, word)
print("在目录{}中，单词'{}'出现的次数为：{}".format(directory, word, result))
