如何从指定目录中的多个csv文件创建单个数据帧

import pandas as pd
import os

directory = '指定目录的路径'

merged_df = pd.DataFrame()

for filename in os.listdir(directory):
    if filename.endswith(".csv"):
        file_path = os.path.join(directory, filename)
        df = pd.read_csv(file_path)
        merged_df = pd.concat([merged_df, df], ignore_index=True)

# 打印合并后的数据帧
print(merged_df)

# 对合并后的数据帧进行统计分析
summary = merged_df.describe()
print(summary)
