挑选出行数足够的excel文件

**

遍历文件夹下的所有excel文件，并将数据量超过指定标准的文件拷贝到指定文件夹中

import os.path
import shutil
import pandas as pd


def copy_excel_files(source_folder, target_folder, row_threshold):
    if not os.path.exists(target_folder):
         os.makedirs(target_folder)

    for filename in os.listdir(source_folder):
        if filename.endswith(
                ('.xlsx', '.xls')
        ):
            file_path = os.path.join(source_folder, filename)
            try:
                df = pd.read_excel(file_path)
                if len(df) > row_threshold:
                    target_path = os.path.join(target_folder, filename)
                    shutil.copy2(file_path, target_path)
                    print(f"已复制文件{filename}")
            except Exception as e:
                print(f"处理文件{filename}时出错：{e}")

if __name__ == "__main__":
    # 源文件夹路径
    source_folder = '自定义路径1'
    # 目标文件夹路径
    target_folder = '自定义路径2'
    # 行数阈值，可根据需要修改
    row_threshold = 50

    copy_excel_files(source_folder, target_folder, row_threshold)
