将path中的所有csv文件作为pandas数据帧读取

import os
import pandas as pd

def read_csv_files(path):
    data_frames = []
    for file in os.listdir(path):
        if file.endswith(".csv"):
            file_path = os.path.join(path, file)
            df = pd.read_csv(file_path)
            data_frames.append(df)
    return pd.concat(data_frames)

# 示例路径为"/data/csv_files/"
path = "/data/csv_files/"
df = read_csv_files(path)
