读取多个文件的有效方法(python)？

import os

def read_files(directory):
    file_list = os.listdir(directory)
    for file_name in file_list:
        file_path = os.path.join(directory, file_name)
        with open(file_path, 'r') as file:
            content = file.read()
            # 处理文件内容
            print(content)

# 调用函数，传入文件所在目录
read_files('/path/to/files')

import glob

def read_files(pattern):
    file_list = glob.glob(pattern)
    for file_path in file_list:
        with open(file_path, 'r') as file:
            content = file.read()
            # 处理文件内容
            print(content)

# 调用函数，传入文件名匹配模式
read_files('/path/to/files/*.txt')

import os

def read_files(directory):
    for root, dirs, files in os.walk(directory):
        for file_name in files:
            file_path = os.path.join(root, file_name)
            with open(file_path, 'r') as file:
                content = file.read()
                # 处理文件内容
                print(content)

# 调用函数，传入文件所在目录
read_files('/path/to/files')
