导入seaprate pandas数据帧中某个路径下的所有csv文件

import os
import pandas as pd

def import_csv_files(path):
    all_data = pd.DataFrame()
    for file in os.listdir(path):
        if file.endswith(".csv"):
            file_path = os.path.join(path, file)
            data = pd.read_csv(file_path)
            all_data = pd.concat([all_data, data])
    return all_data

data_frame = import_csv_files("指定路径")
