前言

一、pandas是什么?

1、需求

指定目录下有若干文件

批量解压

需要汇总包含指定字符的所有文件中的指定数据


2、程序

python 复制代码

                        print("非指定指令")
                except Exception as e:
                    print(e)

    wb.save(output_file_path)

总结

分享:

接受可以让我面对所有的问题,当我感到焦虑的时候,通常是因为我发现自己不能接受生活中的一些人、地方、事情,直到我完全接受了它们,我才能获得心灵上的安宁。除非我完全的接受生活,否则我将无法获得快乐。我不需要再纠结这个世界上有什么需要改变而是关注我自己的态度需要发生怎样的改变;
