循环遍历多个txt文件并统计Python中所选单词的频率

import os

folder_path = "path_to_folder"  # 替换为文件夹的实际路径

for filename in os.listdir(folder_path):
    if filename.endswith(".txt"):
        file_path = os.path.join(folder_path, filename)
        with open(file_path, "r") as file:
            content = file.read()
            # 统计频率的代码

import re
from collections import Counter

word_counts = Counter()

for filename in os.listdir(folder_path):
    if filename.endswith(".txt"):
        file_path = os.path.join(folder_path, filename)
        with open(file_path, "r") as file:
            content = file.read()
            words = re.findall(r'\b\w+\b', content)  # 使用正则表达式分割单词
            word_counts.update(words)  # 统计单词出现的频率

print(word_counts.most_common())  # 输出按频率排序的单词列表
