如何从不同的子目录中读取多个csv文件，并找到具有该值的csv文件？

import os
import csv
import pandas as pd

def find_csv_with_value(root_dir, target_value):
    csv_files = []
    
    for root, dirs, files in os.walk(root_dir):
        for file in files:
            if file.endswith(".csv"):
                file_path = os.path.join(root, file)
                csv_files.append(file_path)
    
    files_with_value = []
    
    for csv_file in csv_files:
        with open(csv_file, 'r') as file:
            # 使用csv库读取CSV文件
            reader = csv.reader(file)
            for row in reader:
                if target_value in row:
                    files_with_value.append(csv_file)
                    break
            # 使用pandas库读取CSV文件
            # df = pd.read_csv(csv_file)
            # if target_value in df.values:
            #     files_with_value.append(csv_file)
    
    return files_with_value

root_directory = '/path/to/your/root/directory'
target_value = 'your_target_value'

result = find_csv_with_value(root_directory, target_value)
for file in result:
    print(file)
