如何在文件夹中查找各种类型的csv文件的列标题？

import os
import csv

def find_csv_column_titles(folder_path):
    csv_files = []
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            if file.endswith(".csv"):
                csv_files.append(os.path.join(root, file))

    column_titles = {}
    for csv_file in csv_files:
        with open(csv_file, 'r') as file:
            reader = csv.reader(file)
            column_titles[csv_file] = next(reader)

    return column_titles

folder_path = "path/to/folder"
column_titles = find_csv_column_titles(folder_path)
for csv_file, titles in column_titles.items():
    print(f"CSV file: {csv_file}")
    print(f"Column titles: {titles}")
