如何在Python for Pandas中读取多个独立的数据帧

import pandas as pd

df1 = pd.read_csv('data1.csv')
df2 = pd.read_excel('data2.xlsx')

# 合并数据帧
merged_df = pd.concat([df1, df2], axis=0)

# 筛选数据
filtered_df = merged_df[merged_df['column_name'] > 10]

# 计算统计指标
mean_value = filtered_df['column_name'].mean()

# 保存数据帧到CSV文件
merged_df.to_csv('merged_data.csv', index=False)

# 输出数据帧的前几行
print(merged_df.head())

# 输出统计指标
print("Mean value:", mean_value)
